The NSX I was looking at was a 1991 manual with 150k

I kinda wish I bought it. NSX under 20,000 is slim pickings let me tell you.
The suggestion about the s2000 is a great one, but I'm 6'3 and 235lbs. I have tried very hard fit and there is no possible way. No tilt wheel and no head room.
The 911 I am looking is a 2000 911 with 50k at 20,000 exactly
I don't really want a 350z because well my friend at one and am looking for something different.
Good suggestions so far. Keep them coming.
