I bought a 2003 F150 from the Ford dealership in Fargo that had obviously been crashed. It only had 14k miles on it, mismatched tires, uncharged AC, and in need of an alignment. It didn't come with a salvage title, probably because it was a Canadian truck, but if you looked close enough you could see most of the front suspension had been replaced. I probably spent 2 hours crawling around that truck trying to get a grip on what all had been replaced. I had the dealership replace the tires, fix the AC and alignment before I bought it. I drove that truck until it had 120k miles on it and the only problem I ever really had with it were coils. I think I had to put 3 coils and an alternator in it over the years.
As with any major purchase, due diligence is required.
