Hi Sharon...I bought my car used with 9,000 miles on it. The history which you can get from the VIN number had the car as a re-po...so, someone wasn't able to make the payments and it was returned to the dealer. It was then sold on consignment by another dealer and I got a great price for it. It was in pristine condition with just a few minor signs that it had been driver. (a minor scratch on the rims).
I know that it would not make any sense for you to buy a new car...obviously, you want your car to be fixed and that's what you should have done. I hope DC comes through for you and that your car is running as beautifully as you look driving it!!!
