No wonder you got in trouble the first time,,, NO,,,

You cannot sell the car without paying the lien holder. whom is the lien holder ?

Did you put any money down when you purchased this car ? How many payments you got to go ? what model is the car ? how many KM on vehicle now ?

GMAC financing, 1500 down, 11k miles, 5.5 yrs left

OUCH - that works out to $34,620 you paid out the door.

Nothing is going to work in your favor, but if you want let's look at the overall picture to see what your best approch may be.

For starters phone GMAC tomorrow and request a payout amount.

if you want our conversation not to be public email me with the amount, your choice.
