The worst car purchase experience I had from this dealership.
Too rude behavior of the staff. and less knowledgeable. they only care about getting the money.
They completed the transaction without the second key when they said the key will be given next day, then when they got the money from the bank, they said, there is no key, after 2 months of followup, and fighting they finally gave the key. The registration documents they have given after 1.5 months after several followups.
