Budman,

Beside the routine checks for a used car, you might want to see the technical service bulletins for the 97/98 GTP sedans. The titles are available at Alldata.com for free. I have a 98 GTP Sedan with 25K bought new and I did have some of the minor listed problems. Fortunately they were fixed under warranty. Also take a look at the battery if it is the original unit and check the passenger side for any water leaks.

If the car checks out ok, have fun!
