I just bought a 2009 Ram 1500 with about 95,000 miles, 5.7 V8 hemi, for about $15K. That is about what you can expect for that kind of money. I have an F250 with 165,000 miles on it and I expect to get at least 200,000 miles out of it. I would probably get more but it is already 15 years old and body and interior is wearing out. Typically, the mechanical aspects will be fine with regular maintenance but the body and interior will wear out. I had a blazer that I would have kept but I would have had to put floor drains in it to get the water out after every rain. Fender wells, window and door seals and other similar stuff just wear out.
