i think if it was me id just have this one repaired if its not a real high mileage vehicle,you can repair it cheaper than you can buy another vehicle,and think of it like this,you only have 6 more payments on it,so that's something to consider,before i went back in debt again id really think this one through,you know the car better than i do though ,and do you think its worth repairing,? good luck with it.
