The bottom line
Buy the engine first. Oil leaks hit 64% of these cars, with fuel-trim and coolant issues close behind, so start with seepage, coolant level, and a live fuel-trim read — a smooth idle does not clear it. Cleared codes run ahead of the wider fleet, so a dark dash is a weak promise; if they will not allow a full scan, walk. Worn tires belong in the price. Paint and structure look ordinary, so do not walk over a respray if the powertrain and electronics check out, and do not pay up for a mediocre example.
