Start every purchase in the calculator

Open the flip-profit calculator. Plug junkyard price (J), starting condition (C0), target condition (Cf), paint cost (P), and buyer route. The tool returns a BUY / MARGINAL / SKIP verdict before you spend.

Aim for 85-100% condition before sale

Per Radex Tips and Berlian Kecil, cars above 85% condition keep full resale premium. Stop repairing below 85% only if you can reroute to a lower-paying buyer fast.

Always run the negotiation ladder

Juan and Mr. Lupin both support negotiation rounds. Run two rounds minimum on Juan (default buyer) and the full ladder on Mr. Lupin (tier 4-5 only).

Avoid Rick unless time-pressured

Rick pays ~62% of true value with no negotiation window. Use him only when the server is closing in the last 60 seconds.

Compounding loop

Once you clear 80,000 Cash in the bank, switch from Shavlon Spark (tier 1) to Civix RK (tier 2), then Mercer M21 (tier 4). The cascading resale premium funds tier-5 hunting.
