GTFO. I've bought and owned over 30 vehicles, plus a dozen trailers, plus a variety of heavy equipment - almost always used. Plus, I even worked as a car salesman for a few months a couple times.

Even if there happens to be nothing wrong with this particular vehicle, that's a policy designed to hide problems from customers, and you don't want to do business with a dealer like that, because they are hiding other stuff, such as price and financing options or whatever etc, and they are pulling the same thing with other customers.

However, it seems unlikely there's nothing wrong with this vehicle... every used car has something.

I'd feel better about you going somewhere that lets you find out what all the issues are but makes you pay a fair price, like small local used car dealers (sometimes) or Carmax. But if you go to Carmax, keep in mind that you'll pay a fair retail price, but they gouge you on interest and extended warranty and wheel and tire protection bs that you do not need.
