Junk Mechanics Game Passes and Store Guide

Junk Mechanics is free to play, and you can reach every part of the core loop without spending Robux. The Store sells convenience, time and luck. This page lists every game pass and item with its price as shown on Roblox, explains what each one does, and says plainly which purchases are worth considering and which are not.

Quick answer

VIP is the only pass that increases earnings; everything else is convenience, storage or luck

There are four game passes: VIP (399 Robux, +10% Cash from car sales and driving plus a chat tag), Premium Garage (399), Big Inventory (179) and Portable Jack (199). The Store also sells Cash packs from 49 Robux for $12,500 to 4,999 Robux for $1,800,000, Premium Auction Keys, junkyard rerolls, two limited cars and items for Cars & Bids. If you play a lot and flip constantly, VIP is the purchase that pays back. Auction keys and rerolls are luck, not value.

PassPrice (Robux)What it doesWho it suits
VIP39910% more Cash from selling cars and from driving, plus a VIP chat tag.Players who flip a lot.
Premium Garage399An extra garage, shown on the map since late August.Collectors short on space.
Big Inventory179Raises how many parts, rims and spare engines you can carry.Builders who hoard parts.
Portable Jack199Place a jack anywhere and lift your car, intended for swapping wheels away from Tire Zone.Builders who change rims often.

The three passes available in early August (VIP, Portable Jack and Big Inventory) totalled 777 Robux when a creator bought them all on camera, which matches today's prices. Gift versions of each pass are also sold if you want to buy one for a friend.

Is VIP worth it?

VIP is the only pass that directly raises earnings. Ten percent on every sale adds up quickly if you are flipping cars for hours, and it applies to driving income too. In the August review the creator sold a 100%-condition rare car to Mr. Lupin with VIP active and negotiated about $405,000, while a player in chat estimated around $350,000 without it.

If you only play occasionally, the boost is small in absolute terms, and free habits (painting every car, repairing to about 85–90%, and using the right buyer) matter more. The selling guide covers those.

Rookie Bid, Amateur Bid29, 79Added October 3 with Cars & Bids. Exact effect not described in the Store.

Bigger Cash packs give more Cash per Robux, but compare that with what a single good flip earns. One restored rare car sold to Mr. Lupin can be worth more than the smallest packs combined, and it costs nothing but time.

Limited cars: buy or skip?

The two limited cars are sold in the in-game shop and marked as limited, but a creator pointed out on October 2 that there is no countdown showing when they leave the shop; the Cobra RT500 had been on sale since mid-August. That makes it hard to judge urgency.

  • Buy one if you love the car and want it now, not as an investment.
  • There is no trading system to resell limited cars when this page was checked, so rarity does not turn into Cash.
  • If you want a fast car without Robux, a junkyard car with a good engine swap and tune can get close; see the engines guide.

More on limited and auction-only cars is in limited and exclusive cars.

Sources and how this page was checked

All prices and item names were read from the Junk Mechanics Store on Roblox on October 5, 2026; Roblox prices can change at any time. What each pass does comes from a creator who bought and tested every pass on camera (August 5, 2026) and from later update videos. The Store does not describe most items, so where an effect is not documented we say so.
