Excellent car. Bought it from my uncle for $1500. Unfortunately it developed an electrical problem affecting the engine, not to mention an engine coolant leak only 2 months after I bought it. Was told it was due to the car's age but, the previous owner took excellent care of the car. Everything still factory.
3800 V6 Engine. Nothing like that quick burst of speed. Really comfortable ride.
Nothing really to improve upon. (Especially considering Oldsmobile doesn't exist anymore.) Was an excellent car for it's time.
