What can you do if you have a child on the way and your car payments are now too high to afford but you got a great rate at 2.9 when you bought the car?

Sell the car person-to-person. Never take it to a dealership to sell or trade, you almost never get what it is worth. If you cannot sell the car, try refinancing. You'll get a higher APR and pay more interest in the long run, but you can extend payments and keep your car (plus afford the payments). give the car back buy a 500 dollar special, spend the car payment on the kid
