What Junk Mechanics is about
Junk Mechanics is a vehicle-repair tycoon by developer Oil Leak. You buy damaged cars from the junkyard, repair every part to 85-100% condition, optionally repaint, and sell to one of three buyers: Juan (negotiator), Rick (underbuyer), or Mr. Lupin (luxury; tiers 4-5 only).
The six-step loop
Buy in the junkyard → Inspect (open the hood) → Repair (weld, clean, replace each part) → Charge the battery at the charger station → Repaint at the Custom Shop → Sell to the right buyer.
Start with the cheapest car
Walk to the junkyard, target a Shavlon Spark at ~9,000 Cash. Spend your first three cars on repair practice only — no paint, no Mr. Lupin yet.
Treat codes carefully
Roblox does not publish an API for promo codes. The codes page tracks community-reported codes (THIRDCODEOK, FOURTHCODINITUNGTUNG, ELCINCO) and asks you to redeem them in the SHOP menu after you sell your first car.
Use the calculators as planning models
The four tools (repair-cost, flip-profit, paint-ROI, junkyard-search-strategy) are planning models. Always run a calculation before clicking Confirm Purchase at the junkyard.
