If you ever sold anything on Craigslist that might be one of the reasons people rather sell to junk yards no bs and no safety issues.Damn, that's a shame. Why would someone take scrap iron price for a running car that was in good enough shape for someone to cut the whole floorpan out of?
I live in California I've seen plenty of nice cars and trucks in the yards. It's California where you have to smog your car if it's newer than 1975. Many cars are junked just on that basis. The local yards pay like 100-300 for most cars and trucks. They don't just base the price on scrap weight they also price it based on the popularity of the vehicle. Junk yards sell cars but will carry a salvage title. They don't sell everything although I have heard that if you want a car from the inside the yard you can buy but be prepared to pay for it. As others have mentioned once it gets processed to go in the yard they will get damaged from workers or forklifts or both.
