Funny you mention this. In my professional life, I deal with tow companies pretty regularly. I was at the biggest company in our area on Wednesday and was talking to the owner about how to get rid of my rusty stripped Tundra when the time comes.
I mentioned cars for kids and he explained it to me. They are a middle man. They get the request from owner of the car for removal, then try and sell it to a tow company to go and pick it up. He said it’s a total scam. They do nothing but connect the tow company with the owner of the junk car and then take the majority of the money. The tow company takes all the risk. I bet they will got something for your 4Runner, just not enough to give you any.
The good news he said he will take my rusty stripped Tundra for nothing and pick it up. He gets $100 for a car/truck with no drivetrain and $400 for a compete car/truck at the scrapyard. He does enough business to run a 4 car trailer to the scrapyard almost every day.
