So im looking at buying this 87 GT it has 119k. He says its pretty stock which is what im looking for. he says it comes with a rebuilt 306. just trying to figure out what its worth. He says its for sale on craigslist for 4500 but i couldnt find it. (he answered my ad) i asked him to email it to me and he said he had to remake it so im getting the feeling he might over value it on the ad to try to pull the wool over my eyes. just trying to get an idea of what its worth. here are pics.
