I sold a guy a car a couple days ago and now hes having problems with it. It was an 89 240sx i had been using as a daily driver. I've never had any problems with the car at all. I've taken long trips in it, from mobile AL back and forth to atlanta and so forth. It's an 89 car, it's obviously not a ferrari but it ran good. I let the guy testdrive it as much as he wanted, looked it over the whole nine. Sold the car, everything seems to be ok. A couple days later he calls me and says he's having some major problems with the car, that the engine is knocking as so forth and asks if there's a possibility i could buy it back.

I've never been faced with a situation such as this, so im not sure what the standard procedure is. My first guess is that the new owner may have driven the car a little harder than i normally would and with an 89 vehicle, anything can happen. I'm not sure what to do, i want to be friendly, the buyer seemed like a nice guy and i dont want to do anybody wrong, but what are my options here? I sold a car that left my house running good and now its appearantly tore up. I dont have the $ to buyback or repair a vehicle otherwise i wouldnt have been selling it in the first place.

your thoughts?
