ksl. The guy that bought it apparently thought he was buying a side by side with a different size engine than what mine had. He was looking for a 660 and mine is a 450. He came to my house, looked it over, started it up, took it for a ride, and bought it. Now this morning he texts me demanding that i reverse the sale because he thought it was a 660. I told him no, and now he thinks I'm some shady character. He tells me "karma comes back around, i wish you the best of luck my friend."

It could have been a threat, hopefully not.

Regardless, what's the right thing to do here?
