Hi im considering buying a 2006 GT with only 24k miles on it, never seen snow, barely driven. Lots of upgrades, x pipe, performance chip, under pully, tower brace, and its in mint condition. They want $15000 for it, private seller. Do these cars have a lot of repair issues since its off warranty? Im worried about some costly repair, even though i probably wont own the car for much more than a year before I get sick of it and get something else. I just dont want to have to pour a lot of money into it. Thanks!
