I knew a guy who was big into building Hummer replicas, set on full size Suburban frames from the late 90's.
He'd buy insurance wrecks, usually ones that had been rolled, where the frame was straight but the body was just too jacked up to fix reasonably.
Seems like the nicest one he ever bought didn't cost more than $2,000.. and he made more than his $2,000 back selling the seats, factory radio, and other interior things on eBay (that he wasn't going to use, anyway)
So if you want old school look with modern day drivetrain and convenience, buy alater model insurance wreck, strip the wrecked body off, and sell all the decent parts off the body and interior on eBay.
For sure it isn't a quick process, but if you do the work yourself, i'll bet you could get it done within a few months, and your final cost wouldn't be a whole lot.. hell, you might even MAKE money on the deal!
