Hi everybody! A few hours ago I just bought a 97 Deville for $700. Originally it was priced for $1,000 but the guy let me take it for $700. Obviously, the car is not in the best of shape. The guy told me the battery would need to be replaced. Sure enough, after driving it twice, the next time I went to start it it didin't start. No big problem. Gotta get a new battery. Other than that, the car seems to be running pretty good. The most I punched it on the road test was 50mph, and like I said, it was pretty smooth. The breaks were good. The only thing that concerned me was a faint smell of gas and the "service engine soon" sign was on. Could these two things be major problems? During this time the tank was basically running on fumes. I put gas in it later. After I got home from the gas station, parked it, and chilled for a little bit, I started it and the "service engine soon" sign was off. Took it for a lil ride, parked it. Then I tried to start it again and it wouldn't start. And now the "service engine soon" sign is back on. I just want some insight into my purchase. I mean, I don't expect much of $700, but can I at least expect to be driving this car for say 6 months? A year? It has 96,000 miles on it, which is pretty low considering the year, right? I really had to purchase a car for work and school. Didn't really have the option to wait for something better to pop up or do my homework before I made the buy. After reading some of the stuff on this forum about the head gaskets and engine problems with these cars, I'm a little concerned. I definitely cannot afford any major repairs. So, can somebody please just let me know what they think about this car? What is one sure and simple to find out if there is an issue with the head gasket in my car? Please keep in mind I'm a total rookie when it comes to cars and mechanics. Thank you very much.
