when you roll negative equity into a new loan banks will only finance a certian percentage of msrp, usually 110%. If you were to buy a neon (which has a 3000 rebate) you could only finance roughy 18500. which is 110% of a 16000 neon. (median price range.)with taxes. To get out of a 20000 negative equity situation you would need to purchase something Itialian, with a prancing horse on the grill. Unless you have a massive amount of cash down its 711 a month for you or the blow torch! Good luck and congrats on the new arrival.
