I'm happy with the car but the customer service is really bad.
They messed up the paper work and I had to go and spent 1 hr more to sign papers again.
In addition they didn't have the DMV paperwork ready. When I went to DMV to get my plates they told me that the dealer didn't have my name assigned to the car...
So I lost many hours from work ... not happy.
