What makes a Tier 5 hard to get
Cars in Junk Mechanics are grouped from Tier 1 to Tier 5, and the in-game index colour-codes them so you can see each car's tier. Tier 1–3 cars are the everyday flips. Tier 4 and Tier 5 cars are rare, sell for the most at Mr. Lupin's luxury dealership, and are the reason most players open auctions at all.
Junkyard spawns run on a timer, and a Tier 5 is a small slice of those spawns. Auctions roll from a prize pool where rare cars have low odds. That leaves you two levers: more rolls per hour, and better odds per roll. Every method below pulls one of those levers. None of them guarantees a Tier 5.
Every Tier 5 route compared
| Route | Lever | Cost | Notes |
|---|---|---|---|
| Industrial and Elite junkyards | Better odds | Higher car prices | Added September 20; the Industrial junkyard greets you with "Better junkyards, better spawn chances for rare car." Elite showed about 5 million total value on screen. |
| Buy-and-quick-sell respawn trick | More rolls | The loss on one quick sale | Buying a car and selling it straight away is reported to trigger an extra respawn 5–10 seconds later. |
| Junkyard rerolls | More rolls | Robux per reroll | Replaces every car in the yard at once. The Store lists items named Junkyard 1 to Junkyard 4 at 39, 39, 79 and 129 Robux; they appeared alongside the new yards and line up with a reroll per yard. |
| Premium auctions | Best reported odds | Premium Auction Keys | Spend free keys from codes and tasks first. |
| Cash auctions | Some odds | In-game Cash | High variance; see the session example below. |
| Cars & Bids | Known car | Your winning bid | Hourly player-vs-player bidding at the luxury dealership since October 3. |
| Wait in a junkyard | Time | Free | Slowest, but free. Flip lower tiers while you wait. |
The respawn trick and rerolls only add spawns. The creator who popularised the trick was explicit that it does not increase your luck. The odds per car come from which junkyard you are in.
The junkyard route in detail
- Build up Cash with normal flips until you can afford cars in the Industrial junkyard, then the Elite junkyard. The junkyard guide explains each yard.
- Stand where you can see the spawn spots. When a car spawns, the notification tells you which junkyard it appeared in, and rare spawns are announced in chat.
- If the yard is full of cars you do not want, buy the cheapest and quick-sell it to trigger an extra respawn.
- When a Tier 4 or Tier 5 appears, buy it immediately; other players in the server can take it.
- Restore and paint it, then sell it to Mr. Lupin or keep it for your collection.
Quick travel (added September 20, paid since September 26) makes it faster to hop between yards and garages, but it has a cooldown and you cannot use it while sitting in a car.
The auction route in detail
Premium auctions are the method community guides rank first for raw Tier 5 odds. They need Premium Auction Keys: free from some codes and from daily and weekly tasks, or bought in the Store from 99 Robux for one key to 2,999 Robux for fifty. The game itself warns that auctions are not meant to be profitable.
Cash auctions are the free-to-play gamble. In a recorded September session one player started with about 5 million Cash and opened auction after auction; they came away with two Tier 5s and a few Tier 4s, but also a pile of low-value cars, and spent millions doing it. That is a realistic picture of the variance.
Remember that, as of October 3, the CLK-style and LFA-style Tier 5s are auction-only, and a Huracán-style car arrived through premium auctions and Cars & Bids. If you want one of those specific cars, the junkyard route cannot give it to you. Full details are in the auctions guide.
A plan for your budget
| You are | Plan |
|---|---|
| New and free-to-play | Flip in the starter junkyard until you can afford Industrial cars. Redeem every key code and finish tasks for free keys. Spend keys on premium auctions. |
| Cash-rich, no Robux | Farm the Elite junkyard with the respawn trick. Treat cash auctions as entertainment with a fixed budget. Watch Cars & Bids for cars worth more restored than your bid. |
| Willing to spend Robux | Rerolls give the most junkyard rolls per minute; premium key packs give the best reported odds. Set a spending limit before you start. |
