I bought a new car for a month and wanted to return it
Following up on @petebelford's answer: If you can find a less expensive loan, you can refinance the car and reduce the total interest you pay that way. Or, if your loan permits it (not all do; talk to the bank which holds the loan and,/or read the paperwork you didn't look at), you may be able to make additional payments to reduce the principal of the loan, which will reduce the amount and duration of the loan and could significantly reduce the total interest paid ... at the cost of requiring you pay more each month, or pay an additional sum up front. Returning the car is not an option. A new car loses a large portion of its value the moment you drive it off the dealer's lot and it ceases to be a "new" car. You can't return it. You can sell it as a recent model used car, but you will lose money on the deal so even if you use that to pay down the loan you will still owe the bank money. Given the pain involved that way, you might as well keep the car and just try to refinance or pay it off. Next time, read and understand all the paperwork before signing.  (If you had decided this was a mistake within 3 days of buying, you might have been able to take advantage of "cooling down period" laws to cancel the contract, if such laws exist in your area. A month later is much too late.)
