Neven that price does seem kind of high without numbers matching. Is it a 68 or 67? If it is a true 67 400 convert it will command a higher price because just over 15000 converts were built that year. For the 68 year many more were built thus lowering the price it may be able to get, in my book. Sounds like he may have put some money in the car ( 400, 5 speed trans), but unless it was a rust free car from a desert state i would keep looking. For some odd reason when i was scouring the web for a hot rod to buy the first gen camaros would always seem to be fetching a higher price than first gen firebirds. So bang for the buck, and luck is why i own and like FGF,s. Their not making anymore pontiacs so i would only think the prices should start to go up down the road. So if this car that you saw is bad [censored] and the timing is right for you to own a project than go for it. This is a great site to learn from. I am located in IL too.
