The bottom line
Expect oil leaks and a resprayed panel on most of these. Pop the hood first and hunt for seepage, then scan for fuel-trim problems and recently cleared codes. Crawl underneath for torn bushings and worn joints, and don't ignore the tires. With nearly nine in ten cars showing at least one repainted panel, inspect gaps and overspray like a detective even though actual structural repairs stay rare. If the engine is already leaking and the seller acts surprised, walk or knock a chunk off the price; only the clean, dry examples are worth chasing.
