Yeah, just ask the owner a lot of questions.. anything you want to know. Check the body out inside and out throughly (which unfortunately I didn't do for my 'Formula) and run the VIN to make sure what it originally had such as engine hasn't been switched out (I was told the Formula had a rebuilt 350 put in.. when I ran the vin and compared the engine tag, they matched. You can get a car fax report on it if you would like.. sometimes you get lucky. Not sure where you are from, but salt for ice does a number on these cars. Better to find one where snow isn't a problem. But any problems you run into, many of the people here will be able to help you through them. Just do your research before you buy it.
