I bought this old '81 Suburban a few years ago with dreams of restoring it.  Unfortunately, the money never turned up to do some real work on it.  It's been converted from gasoline to run on butane.  My dad is the only one that uses it these days to drive to his farm, he loves it and refuses to sell it.  It doesn't have any A/C, the rear glass is missing and the body has quite a bit of rust now but he has kept it running and it works just fine for him.
