Should I do this or not?

[GMC406]

Found for sale local a 49 5 Window GMC close by. I make the drive to see it and find out for 1 its a chevy. (the owner was suprised to find this out by the way, aparently the three large chevrolet emblems on the hood didnt get the hint accross) For starters I would like a GMC better but I digress. As of the moment it is just a cab on a chasis. He has all body parts(he thinks) Hood looks good. One fender is slightly damaged. All straight glass in cab is busted but corners are good. No rust in cab. Beautiful griile that was kept inside and polished. Firewall and interior have been painted. It has a grand prix rear axel and front end on it. The frame is welded together right in front of the cab and apears to have been done rigidly. The bed is completly disasembled fair at best and possibly not all there. All I seen was the sides, fenders and front peice(wich was scatered all over under weeds covered in mud ect) and as of now he can't find all the interior peices. I dont see how with the front frame the front clip would bolt on but he said it was together and driven not all that long ago. His ad says he wants 1000, he told me over the phone 750 and when I was lookin at it he said he might take 500. I dont need it now, but I love the 5 window trucks and would hate to let a good deal pass. What you guys think? here is a link to the ad if it helps http://www.thenex-techclassifieds.co...257325&cpage=8
