The chev sounds like a good deal if you ask me, he's been fixing it up and looking after it so you know if you buy it you won't be nickle and diming it to death. So what if it has differant pannels, the truck has huge potential, it just needs paint!, anything you buy will need repair unless it's new, besides you can get parts for a chev at the local kwiky mart!, I got 298,000 on my chev and still lots of oil press, and I drive it hard!! Worse case senario it needs an engine, big deal they're a dime a dozen.
I tend to stay away from dodges, they can't put a tranny in anything they always break and parts are way more then the chevs!
Go for it!
