Im look at a 2002 GT 5 speed with 90 thousand miles. It sounds good but has one issue im worried about. He says is smokes when you rev it or pull away after about 30 seconds of idling and dosent smoke anymore after revving of pulling away. He said its all most like it builds up while idling. He said it started doing that after he removed the cats, but will do that after warmed up. Could it be valve seals or just moisture? Should this be a reason not to buy the car? What would it cost and how hard to fix if its valve seals? Also any other things to look for when buying this kind of car?
Thanks
