Man, that really sucks, especially when you definitely wanted the car.
I've bought a few shit cars from crazy people, and all those small lots seem to either be the most awesome, chilled out people in the world or completely crazy dipshits that talk about ni**ers, jesus, how muslims all need to die or how "thank god you're not mexican" and other crazy shit that you don't even wanna hear. I'm amazed they stay open, too.
Asshole probably bought the car for $2500 too
