Salesman seemed completely uninterested and seemed unhappy working there. When I test drove the car, it was disgusting and hadn't been cleaned from previous owner. When discussing the price, he immediately said they don't negotiate and he gets nothing regardless if I buy a car there or not. When I returned the car, I went to another dealership and got better service and a better deal; if he gets nothing anyway, let it also not be my business. Wouldn't recommend.
