I did something stupid

I have only once bought a car sight unseen, drove 650 miles three days later to pick it up and drive it home. It was a very good deal and overall a good experience. The seller represented the car fairly, answered all of my questions honestly, and I guess I was fortunate to find a good seller. He had dozens of positive reviews and only a few negative ones. The car wasn't perfect, I did have to do some things to make it pass a mechanical inspection when I got home, but it did not have any problems on the drive home. Plus it was a nice little vacation for my wife and I.
It's really unfortunate that the op has been through such a tough situation with what should have been a good experience. I hope that you take a little time to really consider whether you really want to sell it or not before you end up regretting that decision.
