Mini 4WD Nostalgia: 5 Rare Finds on Japan’s Mercari, and How to Get Them to Singapore
📌 TL;DR
・The toy that shaped a generation of Singaporean kids is still findable today: the discontinued Mini 4WD kits and upgrade parts from the Let’s & Go!! era never disappeared — they just moved to a different market.
・Local hobby shops only stock current stock: discontinued bodies and limited-run parts haven’t been on anyone’s order list for years.
・Japan’s Mercari has the largest secondhand supply: it’s a resale marketplace by design, which is exactly why these old items surface there.
・The catch: Mercari requires a Japanese phone number and local payment methods — overseas buyers can’t sign up or check out directly.
・The fix: Buy&Ship’s proxy shopping service — send us the listing link, and we handle contacting the seller, payment, and shipping to Singapore, no Japanese phone or credit card required.
An English dub of Bakusō Kyōdai Let’s & Go!! — released internationally simply as Let’s & Go!! — aired on Kids Central, Singapore’s children’s channel under MediaCorp, and that’s how a whole generation of local kids first got hooked on Mini 4WD racing. It was part of a wider craze across the region in the 1990s, alongside neighbouring Malaysia, where Tamiya Mini 4WD racing became one of the biggest hobbies for boys aged 8 to 15. That wave has long since passed, but the actual kits and parts from that era never really vanished.
The problem is that hobby shops in Singapore stopped restocking these discontinued bodies and parts years ago. Japan’s secondhand marketplace Mercari, on the other hand, is built for exactly this kind of resale — it’s currently the easiest place to track these old items down. Here are 5 worth looking out for, and how to get them shipped to Singapore through Buy&Ship’s proxy shopping and forwarding.
⚠️ Heads up: Mercari is a Japan-only secondhand marketplace, and sellers generally only accept Japanese phone verification and local payment methods — you can’t register or check out from overseas directly. Buy&Ship’s proxy shopping service handles this for you: send us the listing link, and we take care of placing the order, payment, and forwarding to Singapore.

Why Mini 4WD is still worth chasing
Mini 4WD is the proper name for these small motorised racing kits, made by Japanese model manufacturer Tamiya since 1982, with cumulative sales in the hundreds of millions worldwide. In Singapore, much of that popularity traces back to Let’s & Go!!, dubbed in English and aired on Kids Central — the story of two racing brothers whose Japanese names, Retsu and Gou Seiba, are a play on the show’s own title (“Let’s” and “Go”).
What’s easy to forget is that Tamiya never stopped making Mini 4WD — new station-exclusive and anniversary releases are still coming out in 2026. It’s the era-specific kits and discontinued upgrade parts from the original craze that have become genuinely hard to find, not the hobby itself.
Local hobby shops have limited shelf space and generally only order what’s currently in production — discontinued kits haven’t been on anyone’s restock list for years. That’s where Japan’s Mercari comes in: it’s a secondhand marketplace by design, with a much larger pool of old, resold stock than any new-goods retail channel.
5 Mini 4WD finds on Japan’s Mercari
These 5 are ordered from “classic protagonist bodies” to “rare limited-edition collectibles” to “discontinued upgrade parts” to “an official anniversary release” — from the most direct childhood memory to a few things even long-time fans might not know.
❓ First, the obvious question: why not just order from a local hobby shop?
Because you can’t. Local hobby shops have limited shelf space and only stock what’s currently in production — everything on this list has been discontinued for years and isn’t on any distributor’s order list.
In other words, this was never a choice between “local shop or a Japanese webstore” — these kits only exist in the secondhand market now. And among secondhand marketplaces, Mercari wins on sheer volume of local Japanese sellers — discontinued bodies, limited merchandise, and parted-out kits all show up here.
Each pick below is listed with its original official price or historical background for comparison, plus a Mercari reference price to help you judge whether an asking price is reasonable. Mercari is a floating secondhand market — prices vary a lot depending on condition, whether the original box survives, and whether it’s built or unbuilt, and discontinued or limited items commonly sell above their original retail price. Always check the live listing price before ordering — the reference prices below are converted from Mercari’s own official Hong Kong cross-border storefront (hk.mercari.com), using the current HKD/SGD exchange rate, and shown in S$ purely as a value benchmark; the amount charged for a Singapore proxy shopping order will be based on the seller’s actual JPY listing price on jp.mercari.com plus Buy&Ship’s own service fee and shipping, quoted to you in SGD.
🔥 1. Magnum Saber, original release (Super-1 chassis, Fully Cowled Mini 4WD No.1)
💰 Mercari reference price: S$28 – S$90
Original Japan retail price ¥858 for comparison｜kit No.19401, released 7 September 1994｜fully built, boxed examples mostly sell above S$80
The ride of Gou Seiba, the younger brother in Let’s & Go!!, and also the very first kit ever released in Tamiya’s “Fully Cowled Mini 4WD” series. It uses the original Super-1 chassis, the starting point for every chassis generation that followed. This original spec has been discontinued for years — Tamiya’s current lineup only carries the later “Premium” reissue, built on the newer Super II chassis, which is a different platform, not the same kit.
Why it’s worth getting: if you want the actual original release, not the later reissue, the Super-1 chassis original spec is only findable secondhand now. That’s on top of it being the series’ very first kit — a genuine piece of Mini 4WD history.
2. Sonic Saber, original release (Super-1 chassis, Fully Cowled Mini 4WD No.2)
💰 Mercari reference price: approx. S$68
Original Japan retail price ¥858 for comparison｜kit No.19402, released alongside Magnum Saber｜fewer clean single-item sales seen — this is one unbuilt, period-original listing
The ride of Retsu Seiba, the series’ protagonist, also on the original Super-1 chassis and the series’ second-ever kit — the other half of the “brothers” pairing with Magnum Saber. The brothers’ contrasting racing styles, attack versus balance, are one of the most memorable parts of the show for a lot of fans who grew up with it.
Why it’s worth getting: the two brothers’ rides really should be collected as a pair. Like Magnum Saber, this original spec is discontinued — completing the set is a common goal among collectors.
⭐ 3. Emperor Gold Body (event-exclusive)
💰 Mercari reference price: approx. S$17
Original was event/Harajuku “Dragon Shop” exclusive from 1988–1990, no public retail price to compare｜this reference price is for the 2007/2021 reissue set, not a standalone original gold body
A generation before Let’s & Go!!, the earlier series Dash! Yonkuro (which aired in Japan in 1989) had its own protagonist car, “Emperor” — and Tamiya once released a gold-plated body for it, sold exclusively at events between 1988 and 1990 and at the Harajuku “Dragon Shop” (a physical store tied to CoroCoro Comic magazine), complete with its own clear sticker sheet. It’s long been a legendary item among collectors — the original itself was never reissued as a standalone product. Tamiya only ever brought it back as a bundled extra inside the official “Grade-Up Parts Set Classic Vol.3”, first in July 2007, and again in a second limited run in October 2021.
Why it’s worth getting: this is widely regarded as one of the most iconic discontinued items in the whole Mini 4WD collecting scene — being reissued twice, years apart, says something about how in-demand it’s stayed. Both reissues are themselves long gone from official retail, so secondhand is still the only route.
4. Original Hyper Dash Motor (discontinued upgrade part)
💰 Mercari reference price: S$11 – S$15
Current successor “Hyper Dash Motor PRO” official price ¥528 for comparison (still officially sold today, different packaging)｜this range is for listings clearly labelled as the original, non-PRO version
Swapping in a faster motor was the single most direct way to tune a Mini 4WD back in the day, and the Hyper Dash Motor was one of the classic upgrade parts for doing it. Tamiya still sells a current successor, the “Hyper Dash Motor PRO” (official price ¥528), but the packaging and spec have since been updated — it isn’t the same product as the original. If you want the actual original-era motor, secondhand is the only way to get it. Mercari listings explicitly labelled as the original (not PRO) do turn up from time to time.
Why it’s worth getting: if you already have an original-era body, pairing it with a period-correct original motor is the closest you’ll get to running the exact original setup. Check the listing explicitly says “original” rather than PRO before buying.
5. Cyclone Magnum Memorial (25th Anniversary Edition)
💰 Mercari reference price: S$15 – S$26
Official price ¥1,300 for comparison｜released 2 November 2019, a one-time limited production run｜most sales cluster between S$23 – $25
Tamiya marked the 25th anniversary of its “Fully Cowled Mini 4WD” series in 2019 with this Cyclone Magnum Memorial edition, built on the then-new Super TZ-X chassis, with “FULLY COWLED MINI 4WD 25th ANNIVERSARY” engraved on the underside and fluorescent-green wheels. It was a one-time limited production run — no reprints — and is no longer available through official channels, even though it’s not that old.
Why it’s worth getting: it isn’t only old items worth chasing — this one is Tamiya’s own official tribute to the series’ history, proof the legacy is still being marked. If you want something with that “official stamp” of anniversary significance, this is the pick.
＊Mercari reference prices come from recent sold or listed prices for the same or equivalent item on Mercari’s own official Hong Kong cross-border storefront (hk.mercari.com), converted from HK$ to S$ at the current exchange rate — not a manual estimate, though also not queried directly in SGD (Mercari has no dedicated Singapore cross-border storefront). Mercari is a floating secondhand market — prices for the same item can vary a lot by condition, whether the original box survives, and how a seller prices it, and discontinued or limited items commonly sell above original retail. Always check the live listing before ordering.
＊Important: this reference price is not the same figure as your proxy shopping order total. Mercari’s Hong Kong cross-border storefront has its own conversion and fee structure; a Singapore proxy shopping order through Buy&Ship is based on the seller’s original JPY listing price on jp.mercari.com, with Buy&Ship’s own service fee and shipping added separately — the two paths won’t land on the same number. This column is only meant to help you judge roughly what an item is worth, not to preview your invoice.
＊Official prices/historical background for comparison: Magnum Saber and Sonic Saber’s official price of ¥858 is from Tamiya’s own product pages, cross-checked against Tamiya Shop Online’s current catalogue — which only lists the later “Premium (Super II chassis)” versions, confirming the original Super-1 chassis spec is no longer part of the official current lineup; the current Hyper Dash Motor PRO’s ¥528 price is likewise from Tamiya’s own product page; the Cyclone Magnum Memorial’s ¥1,300 price (base price, excluding consumption tax) and release date are from Tamiya’s own product page; the Emperor Gold Body has no public retail price since it was a 1988–1990 event-exclusive item, and the 2007 and 2021 reissue-set prices are from Tamiya’s own product pages.
How to buy these through Buy&Ship
Mercari is a Japan-only secondhand marketplace that generally requires Japanese phone verification and local payment methods, so overseas users can’t register or check out directly. Here’s how it works: find the item you want on Mercari, copy the listing link, and submit it through Buy&Ship’s proxy shopping order page — the system will automatically pull in the item name, photo, and price. Once you’ve confirmed the details and quote, pay locally, and Buy&Ship handles the rest: placing the order, communicating with the seller, and forwarding the item to Singapore. You don’t need a Japanese phone number or credit card.
For the full step-by-step walkthrough (with screenshots for both the web and app versions), see our separate guide, How to Buy from Mercari Japan in Singapore with Buy&Ship Proxy Shopping . Worth reading through that first, then coming back here to pick out the Mini 4WD items you want.
⚠️ Watch out for fakes and scam sellers: like any secondhand marketplace, quality control varies — check seller ratings, ask for real photos of the actual item, and confirm whether what you’re buying is genuine or an aftermarket modification. For more detailed tips on spotting red flags, see our guide to spotting fakes when proxy shopping from Japan [this is the closest match found on the Singapore site’s sitemap — no direct “avoid Mercari scams” equivalent exists there; please open and confirm before publishing].
How much does shipping from Japan cost?
When you use proxy shopping, Buy&Ship first collects the item’s cost and a service fee — the service fee is calculated based on the item’s price and varies by warehouse, so check the exact figure shown when you submit your order.
Once purchased, the item is delivered to Buy&Ship’s Japan warehouse, and international shipping from there is charged by actual weight, per pound, not per item — which is exactly where consolidation pays off: buying several Mini 4WD items and combining them into one shipment to Singapore works out cheaper than shipping each one separately.
| Actual parcel weight | Buy&Ship Delivery (S$9 first lb, S$7/lb after) | UPS (S$10 first lb, S$6/lb after) |
|---|---|---|
| 1 lb | S$9 | S$10 |
| 2 lb | S$16 | S$16 |
| 3 lb | S$23 | S$22 |
| 5 lb | S$37 | S$34 |
💡 Money-saving tip: individual Mini 4WD kits and motors are small and light, which makes them ideal for consolidation — rather than shipping each one separately, place a few orders, let them collect at the warehouse, and combine them into one shipment to Singapore for the best per-pound value.
FAQ: Mercari Mini 4WD proxy shopping
Q1: Can I still actually find discontinued Mini 4WD kits?
There’s a real chance, but it’s not guaranteed stock. Mercari is a secondhand marketplace, so listings come from individual sellers in Japan and supply shifts over time — this is especially true for discontinued and limited items, so it’s worth ordering as soon as you spot something you want.
Q2: I don’t have a Japanese phone number or credit card — can I still buy on Mercari?
Yes. Use Buy&Ship’s proxy shopping service — send us the Mercari listing link, and we place the order and contact the seller on your behalf. You only need to pay the item cost, service fee, and shipping through your local payment method — no Japanese phone number or credit card required.
Q3: Are there any restrictions on shipping Mini 4WD kits or upgrade parts?
Mini 4WD kits generally don’t include batteries (you’ll need to buy those locally), but whether specific upgrade accessories — like model-specific adhesive or spray paint sold separately — can be shipped varies by item. Check Singapore’s prohibited items list before ordering, and confirm against the specific product.
Q4: Are the discontinued bodies on Mercari genuine? Could I end up with a fake?
Most Mercari listings are posted by individual sellers, so authenticity is something you have to judge for yourself. Check seller ratings, ask for actual photos rather than relying on official promotional images, and compare the packaging and details against the genuine product. See our guide to avoiding Mercari scams for more on spotting the difference.
Q5: Can I combine several items into one shipment to Singapore?
Yes. Once your separate proxy shopping orders arrive at Buy&Ship’s Japan warehouse, you can choose to consolidate them into a single shipment to Singapore — shipping is charged on the combined weight, which works out cheaper than shipping each item separately.
