Nope, they hook you up with the seller and you make the deal... they don't touch nothing. Obviusly, they get some commision for letting it sit on their lot, but the paperwork is between the owner and the buyer.....
I have bought maybe 15 cars from lots, this has never happened or been offered, period. Every time the paper work was from the lot of purchase.
I have never bought from a small time flippers lot, so I could be wrong, or NJ might forbid this kind of transaction.
