OT-Need info on 3000gt

Hey, I think I remember a couple people saying they used to own a 3000gt. A friend of mine is looking to buy one, right now at a '99 VR4. It has 60k miles on it, full warranty, and excellent interior. How much trouble are the turbos in that car, how much trouble is the AWS, should my friend look for a non turbo instead with less miles, or the same thing with less miles?
