GuideRepair & flip loop
Radiator, battery, paint, and dealership-sell steps in a repeatable flip loop.
Standard repairs are the volume game
Radiator and battery flips are cheap and repeatable. Paint and collector builds on marques like the BMW G80 are higher margin but higher variance.
Check the flip value before overbidding
A rare marque can still be a loss if parts are expensive and the dealership price does not move. Run the calculator before committing Cash.
