It's difficult to determine what problems you'll have with the car. I drive an '00 S70 T5 and my wife drives an '00 S70 N/A. at 69K mi I have had to change the shocks and struts, the oil pan O rings, the CD player froze, drivers window doesn't go all the way down but goes down in 5 inch increments and all my door panels are peeling. My wife's car with 60K+ runs beautifully and except for wear items, has not needed repairs of any kind. One guess as to which car has an extended warranty?

I say buy the T5!
