I wish I can give no star.I had a very bad experience.
Before going to this dealership I had the down-payment and financial support ready to buy a car.
I had a target price (which I can afford) and I can be little flexible.
Instead of talking about numbers, they talk about my shirt price, am I single or married, what I do with my salary, etc.
When there was a $1000 difference in our negotiation, they asked if I had a credit card so that they can swipe for the $1000 down payment even before I agreed upon the final price.
They had no idea how to deal with a customer.He walked away even before I could make a decision. Very rude and arrogant. Will never deal with them again!
