Absolutely wrong sales perspective by the sales manager Rick. I put deposit for the car so, they can hold it for me for a test drive a day later. They also agreed that they will give some discount . Anyhove, They discounted the price 1.25% off the sales price of $31,999.00. which is $400. And the reason he explain to us:
There is another offer for this vehicle on the table. And he is ready to pay the full price. So, my offer of $31,300.00 rejected by this gentleman very UNPROFESSIONALLY.
What a waste of beautiful afternoon.
P.s: I am not even sure they can offer the car to another person while it is reserved.
I most thankful to Sales Rep. Steve for his patience and kind help. Will I buy car from this dealership. NO.
