The reason of returning is which we do not need this any some-more as we am withdrawal a USA as well as will starting behind to my home country. The automobile is in great figure as well as we followed a compulsory upkeep which is finished by a play yet a mileage is some-more which 30K already. we have to leave in about 2 months time.

No you can try to sell it but they will not take a car back unless you let them repo it
No. The lender won’t take it back. You signed a 72-month contract and are obligated under the terms of that contract. Should have thought of this before deciding to leave the country, or financing a car for 6 years.
You have to sell the car back to the dealer. Chances are that you owe more on the car than it is worth. This means the amount you get for the car will not be enough to pay off what you owe the finance company. You are responsible for the difference.
You will need to put on your best car salesperson impression and get rid of this before you leave the country.
Of course, if you need 6 years to pay for a car, you can’t afford it, anyway.
