2001 Oldsmobile Alero GLS 4dr Sedan (3.4L 6cyl 4A)
I have had numerous problems with this car, the most expensive of which is the coolant system leaks due to poor design at GM. There's a class action lawsuit on this because it is such a consistent problem on these engines (3.4 Liter). If you have this engine, it will develop leaks. It can't possibly do otherwise since the coolant actually erodes the gasket material. It's simply a matter of time. Now with the wheel and brake problems and the numerous small issues, I have to say this would be a terrible choice as a used vehicle. If you like your money, stay away from it.
Power and handling. No denying it can be fun to drive. Just has too many problems.
