I have a friend that bought a 1998 1.8T, and it's been okay, but not as good as he'd hoped. He's had all kinds of electrical and stalling problems. He thought about trading for a 2.8, but the "Audi locals" told him not to, for fear of gaskets, tranny problems, and even more electrical gremlins.
We wanted an AWD car, and bought the Subie.
