Junk Mechanics Tier List
Junk Mechanics sorts cars into Tier 1 through Tier 5. Higher tiers are rarer and sell for more, and Tier 4-5 cars go to a special buyer. Use this page to understand each tier and how to get a Tier 5 faster.

Quick answer
Community-testedTier 5 is the top car tier; premium auctions give the best reported odds of getting one
Flip Tier 1-3 cars for steady Cash, then chase Tier 4 and Tier 5 cars for the biggest sales at Mr. Lupin's luxury dealership. Since September 20 the Industrial and Elite junkyards give better rare-car chances, and premium auctions are reported to have the best odds per roll; spend free keys from codes and quests before Robux. Full routes are in how to get Tier 5.
Car tiers
Junk Mechanics car tiers explained
Tier labels appear in-game; buyer rules come from community money guides.
| Tier | Best use | Where to sell |
|---|---|---|
| Tier 1 | Cheapest rusty starter flips | Dealer offer (not Rick's quick buy) |
| Tier 2 | Early upgrade flips once you have spare Cash | Dealer offer |
| Tier 3 | Mid-game flips with bigger repair bills | Dealer offer |
| Tier 4 | Rare cars; best for profit and collection | Mr. Lupin's luxury dealership |
| Tier 5 | Rarest cars; slow junkyard spawns | Mr. Lupin's luxury dealership |

Rare cars
How to get a Tier 5 in Junk Mechanics
None of these methods raise your luck; they give you more rolls or better odds.
Buy-and-quick-sell respawn trick
Buying a junkyard car and selling it right away is reported to trigger an extra respawn a few seconds later. It speeds up spawns but does not raise luck.
Junkyard rerolls
A paid reroll refreshes every junkyard spot with a new car. Faster spawns, same luck.
Wait in the Junkyard
Free but slow. Tier 5 spawns are rare, so keep flipping lower tiers while you wait.

Cars with a reported tier
The game shows each car's tier in its index, but no complete public list exists. These are the cars whose tier was stated or shown on camera in a dated video. Names are real-world comparisons; the in-game badges are fictional.
| Car (as described) | Tier | Where it comes from | Reported |
|---|---|---|---|
| Mercedes CLK-style car | Tier 5 | Auction-only since October 3 | October 3, 2026 |
| Lexus LFA-style car | Tier 5 | Auction-only since October 3 | October 3, 2026 |
| Audi RS Q8-style SUV | Tier 4 | Added in the September 12 SUV update | September 12, 2026 |
| Aston Martin-style coupe | Tier 4 | Added in the September 12 SUV update | September 12, 2026 |
| BMW M4-style car | Tier 4 or 5 | Sold to Mr. Lupin on camera, so at least Tier 4 | August 5, 2026 |
If you can see a car's tier in your game that is missing here, please send it through the contact page with a screenshot and we will add it. The wider list of reported cars is on the cars page, and auction-only cars are covered in limited and exclusive cars.
Choosing a car by goal
| Goal | What matters | Suggested approach |
|---|---|---|
| Making money | Tier and condition | Flip Tier 1–3 cars quickly; sell any Tier 4–5 you find to Mr. Lupin. |
| Top speed | Engine options and tuning | Pick a car that accepts a V8 or V10 swap, then tune gears for speed. See engines and tuning. |
| Looks and collection | Model, interior and customisation | Newer and remodelled cars have opening doors and interiors. See the paint shop guide. |
| A specific rare car | Where it spawns | Check whether it is junkyard, auction or Store only before chasing it. |
Why we don't publish an S, A, B ranking
Many tier lists for Roblox games rank every car from S to D. We have not done that here, because a fair ranking needs the same test for every car, and the game changes weekly: engines are added, cars are remodelled and auction pools rotate. A ranking that was right in September could be wrong by October.
What we can say with confidence is how the game's own tiers work, which buyer pays for which tier, and which routes give the best chance at a Tier 5. That is what this page focuses on. When a creator publishes a repeatable speed test across many cars, we will link it and say how it was measured.
