Daily routine

Today's flip routine

A repeatable cash-building loop so you always have a next step — redeem, flip, reinvest, then chase the parts of the game that raise per-car profit.

1
Redeem today's codes
Bank first Cash with any verified codes (active list on /codes).
2
Flip one or two wrecks
Bid under your repair-adjusted cap, run the standard repair, resell.
3
Reinvest into capacity
Add a garage slot or a money-boost gamepass so flips stop throttling.
4
Hunt a target marque
Settle on a rarity you can win (570s / Jesko / M2CS) and build the flip plan.

Realistic expectations: profit per flip comes from your sample run, not a guaranteed price sheet. Consistent small flips beat reckless bets on legend-tier marques.

Codes are verified, not invented

The four active Junk Mechanics codes come from a dated Level Nerds roundup (August 12, 2026). A code only appears here after a current source confirms the reward.

Vehicle stats are community-reported

Civix RK, Mercer M21, and BMW G80 marques are confirmed by August 2026 creator coverage, but exact prices, rarity odds, and repair costs remain community-derived until a creator-owned source or a live test publishes tables.

Claim-state labels

User-facing decisions separate verified facts, reported community signals, disputed claims, and missing source gaps.

Active update cadence

August 5, 2026 shipped four new vehicles, engine-sound revamps, paint materials, camera control, and auction-house automation. This is a game in active launch, so update-sensitive claims get rechecked often.
