He says that every vehicle that gets traded in, no matter how many miles on it, according to the customer it's always highway miles.

At least when I said this, it seemed plauasable to the sales people. I did manage to put almost 40k on the car in 2.5 years. And of course the service records could track every one of my roadtrips, since I was usually there a few days after getting back for oil changes and such.

I have always found sales people treat their customers much better when they act like they just want to buy the object and get out. Hell, my second sales guy at Saturn was offering me discounts, not the other way around .
