I was in a similar situation. Came over, left car, never came back. I wanted $2500 for it but then it sat there so long through a NY winter that when someone came to look at it, they went to check the oil, pulled the dipstick and it broke off due to rust. Needless to say, they didnt buy it.
My parents finally ended up selling it for $600 which i was quite angry about but then it was sitting in their driveway, rusting away, not mine.... so it was fair i guess.
