The 3000GT is one of my favorites... I had one for about a year before it was totaled (not my fault, someone pulled out on me). There are a few things to consider on these:

I had problems with the valve guides leaking. Common problem with this engine in the early to mid 90's.

ECU had a bug in it. It would "clip" in and out quickly due to electrolitic capacitor failure on the ecu board. Also an early to mid 90's bug.

Other than that the 5 speed version is fun. Due to the weight, it wasn't very quick off the line but with a cai and exhaust, it will open up nicely from 60-100+mph. The funnest car to pass people with that I have driven.

The VR4's handle so well. I love the all wheel drive/steering they have. I plan on building another one in the future. Hopefully the near future.

Thats my opinion.
