The bottom line
Treat the engine as the whole deal on a used BMW 5 Series. Oil leaks show up on 59 percent of them, so start underneath and around the powerplant, then check coolant and engine electronics before you even sit in the cabin. Insist on a live diagnostic scan because active codes are common and some cars have already had codes wiped, and walk if leaks, cooling trouble, and live faults stack on the same car. Resprayed panels are typical rather than a crash story given the clean structural record, so use the paint and the engine issues to negotiate, and budget for tires.
