I currently own 2 vehicles with salvage titles. My 2011 Hemi Ram 1500 4x4 had 659 miles on it when purchased for less than half price. A carport had fallen on it and it needed a new box side, windshield, hood and mirror. I also did a little work on the roof, (very minor). I have been driving it ever since without a problem. I also have a 2015 Cadillac SRX Luxury (loaded) that I picked up for about 1/3 of the value. It needed a rear carrier, driveshaft,strut, wheel and a minor dent fixed in a front fender. My wife drives it everyday and loves it. The car that it replaced was a 2015 Cadillac ATS that my wife hit a deer with. That car was also a salvage title and was written off by the insurance company after the body shop screwed up the electronics on it. The insurance only wanted to pay out about 2/3 of the value of a car with a clear title. My wife handed me the phone and the negotiation lasted about 30 seconds. I said they charged me full price for the insurance so they had to pay full price on the value of the car otherwise we were going to court. The insurance rep got back to me about 2 hours later with a much better offer which was $55 more than the lowest that my wife and I had agreed on and because it didn't involve going to court, we took it. So this idea that the insurance will pay out less than what the car is valued at is hogwash. It comes down to what you pay premiums on. Personally I will never by another car unless it is at an insurance auction. The monetary savings are just to high to do otherwise. For the most part I only buy cars that are unbolt, bolt-on fixable for the most part though.
