I had one for 10 years, (92 RT/TT) and put 140k miles on it. Never had any problems with the AWD or AWS. BUT - even if I found a low mileage one now, I'd be real hesitant to buy it. The engine bay was just jam-packed, and was impossible to work on. I suspect that parts may not be easy to find for the AWD/AWS stuff, and there weren't a lot of these made in the first place. I think one of these cars today would be a huge money pit.

Specific answers to your questions:

They are heavy 4000lbs+. It feels like it when you drive it.

They are quick. Factory 0-60 was 5 seconds. Even today that's pretty darn fast. Lots of torque all across the tach.

Overall I never had any major problems with mine. AWD/AWS was flawless, no engine problems, no major maintenance issues at all.

FYI - the RT had the exact same body kit as the TT. The only way to tell them apart is the "twin turbo" script on the side skirts, and the TT had dual exhaust out both sides of the valence in the back, where the RT's only had a single outlet. (Passenger side, IIRC).
