sticky car situation

[crystalhattery]

ok almost a year ago we went to a buy here pay here place to get our 03 ford explorer..so we paid on it..I was sending money orders..then the lady that owned the place where we got our vehicle either went into default and choose to go into hiding. We quit sending payments and thought well when something happens we will have cash to pay if anyone wanted to repo..so nothing happened..then our explorer bit the dust..and we figured save up enough money to get a new one..well we got a letter in the mail form a bank saying that they have obtained the promissory note from the place where we got the car..and our future payments should be send to the following address..and when the car is paid off we will get the title...so after a phone call..we asked if they will be reporting this to the credit bureaus in hopes of helping..and the guy said that the original place didn't report to credit so they may not be able to do so themselves..so here's my question should we continue paying and fix out car even though it will be a pricy fix or just let it go and try for something that will help our credit..?? anyway any advice will be helpful..thanks
