I have owned my 97 Lumina for 3 years. It is the most reliable car ever and I have put 30,000 miles on it and all that it has required has been an alternator replaced and EGR ports cleaned and a MIL bulb changed. I would not hesitate to buy another one. These repairs where not costly and easy to repair (and I'm a woman).
It looks great, it's roomy and comfortable has great acceleration, and for a car this size has pretty good mileage and the alternator did not cost an arm and a leg to replace.
