The bottom line
Buicks tend to look better than they run, with frequent panel repaints covering cars that show no structural repairs at all. Engine issues lead the pack, so make oil leaks, fuel trim readings, and active error codes your first checks on any example—tires and lights come next. Those engine faults give you solid ground to negotiate a lower price, but walk away if the leaks are heavy or the codes keep coming back; fixing a tired powertrain will eat any savings.
