Went over there to sell my old clunker with no functioning radio, AC and electric doors and a dented fender... I got 500 which is what I was expecting from prior internet research. Process was easy and friendly (once we got a copy of our title from the DMV).
The original salesman we dealt with was not really into it though. He didn't look too interested in his job and said something like "when you have your paperwork, you dont even need to deal with jerk salesmen like me, just go to the counter". Maybe it was a joke but with his tone, it felt weird and like a disgruntled employee... could be because we weren't going to buy a car from him.
Good no frills experience when you want to sell your car quick.
