The bottom line
A respray is the default here, not a crash warning — structural repairs do not show up — so do not walk for paint. Put the inspection on the engine and the electronics. Oil leaks are the house special, fuel trim is often out of range, and active codes are still in the computers more often than they have been wiped. Pay for a dry bay and a clean scan; engine noise or a trim fault means walk, or make the seller fund a diagnosis first. Worn tires are common enough to use as a bargaining chip.
