I hear they have more wiggly room in dealing with used cars. I looked on line a while ago for a used car. It was a CPO from a dealer. ( better car, better warranty) I went a little bit out of town to get a better price. I had the car for about 12 yrs. I later found out it was a rental. I did ask where it came from and he did not know, "I will look it up."-he never did. The last car I bought new, since the rebates were very good. It was a on-line special. I would try to get some add-ons like service contracts, extra warranty, oil changes. They may deal more with those options ? good luck !
