Should you make a car payment when your engine has gone bad?

You bought the car. It is "up to you" to maintain the car and drive sanely. If you decided to turf the car over a cliff, that is your right(so long as you make the payments-which you have agreed to beforehand).

To try and withhold payments will land you in court and you will lose guaranteed --so now you are saddled with the court costs as well as the car payment.
