What happens if your approved for an auto loan-then denied, and the dealership has already sold your trade-in?
If you were approved for an auto-loan and then denied, the best thing would be to look for you o get another loan. Look for a good lawyer, so you can get back your trade-in. I would look for another dealer, if I were you.
Looks like you need a lawyers advice
They got to give you another car for the same price as what they gave for your other car or work out another deal on a cheaper car
