well.. to bring this thread back from the dead..
I drove a local guys 94 6spd tonight.. his is pretty well modded (gt42r/272s/rps c/c, etc) and I have to say it was nice.. head room wasn't as much as the mkiii, but the seating position and stuff is similar. Stock seat was comfortable, not as supportive as the mkiii seats.. 6spd trans is nice too. smooth shifts, short throw, and felt solid.. even the rps c/c was nice.. easy to drive, a little noise but not much..
I think i'll be getting one in the near future
to be honest i was expecting more of a cockpit feel though, and it didn't feel like it much.. expected it to be tighter between the door and the center colsole to hold you in similar to the z06, but was pretty wide and roomy.. if not more then the mkiii (mkiii side bolsters might hide a lot of that feeling though)
