Unfortunately I didn't have a good experience with them.
My disappointment was that THEY LACK CUSTOMER COURTESY.
Here's why: I called them on Friday afternoon to change an appointment from 12/30/17 at 10:15 to that afternoon about 3:30 p.m. because a had better free time to test drive
a car I was interested.
It took me about 1 hour and a half of driving with the traffic, so I arrived there about 3:47 pm. While I was walking to the front door there was a staff checking on something on the entrance and as I approached he just turned back Inn and didn't say anything to me, no greeting, then I went right to the front desk in front of the entrance and there was no one to assist me there, so I kept standing in the front desk for about 10 minutes and nobody approached to assist me. Then I did some walk around the hall, looked at some cars, walked through the waiting area then came back to the front desk again and stayed there for a little bit. Then I went to the bathroom and came back. When finally I saw that nobody was going to assist me I went outside and tried to look by myself for the car I was interested on the parking lot, and I found it, But I was so upset with their lack of attention that I came to my car and drove back home about 1 hour and a half again.
They basically had the car I wanted and I was going to buy it but as they didn't give a minimum of attention to me, as a customer while I was there, I'm not going back again.
They didn't even called me yet at least to see if I was going to show up.
Too bad unfortunately.
