I don't know what state you live in but that is not true in my state. Whatever you get for the car counts as a trade-in and you subtract that from the cost of the new car. Better check because that doesn't make a lick of sense to me.

You are best in trying to get the best as a tradein from where you are buying the car....
if you sell it private you are screwed with paying WHOLE tax on the challenger.........
Remember if the dealer gives yea 14,000 on your stang gt and the dodge dealer sells you
the challenger at $30,000.You will pay only $16,000 in tax Only....
If you sell your Stang on your own,maybe you will make a few dollars,,,,But
you will have to pay the full tax on teh challenger.....
Too me its not worth getting annoyed with people coming by looking at the car....
Just get the best tradein
