Switching costs money. From what he said money might be tight. I buy and sell my own vehicles. It is a job. Most prefer to give up a few grand to not have to do it (you never get paid full market value on a trade in). Even if someone decided to do it themselves they run the risk of losing big time if they're inexperienced. Even though I've been doing it for years even I lose on some of these. When I lose, it's usually close to the cost of the vehicle. I can afford that and in the end I average out really well.But the majority of people can't do that. I get all the hate new big trucks get and I agree. As someone who works in construction I wish station wagons would make a come back. But it's really easy to say "just do x y or z" it's not so easy to do.
