I am not real sure, but I got a 91 na about 2 years ago maybe, and it wasn't in real good shape, but I only paid 2600 for it. So the car you are talking about is probably around 4-4500. That is my guess. It all depends on what the car will be worth to you also.
Lot of variables there, man, because an unmolested 2 would appeal to some, whereas a well modded 2 would appeal to others. The opposite, of course, is true, too, because a modded 2 would turn some off but an unmodded 2 would not have freebies others would look for. Ballpark would be 3-4.5K, but there are exceptions as I know of a guy who bought a nude 2 for $500 that only needed an alternator yet others would pay 5K if they were real desperate. I got my stark '91 na 4 years ago for $3,500 with 113k on the clock with a cracked windshield.
thx just looking at ballpark, buddy of mine has 91 na, with spun rod bearing, selling it tryin to see if it is worth it, as i have a rebuilt 5sfe sitting in the shop... maybe thinking bout resaleing but dont want to waste alot of money, dont want to make alot of money, just want both of us to get what we want, my block sold and his car sold... lol,
