I had a great buying experience at MB of HV (now AutoNation), from start to finish it was a class act. The three main folks I dealt with were Joon, Hamid and Joe in service whom all were very accommodating.
My purchase was hassle free and Joon and Hamid worked me out a more than fair deal and I did not feel pressured or hassled at all. Within my first week of ownership I received several calls to make sure I was happy. I discovered my AMG pulled a bit to the right on the highway which sent me in to service. The service area was very nice, multiple areas to work or relax, they had a nice starbux machine with snacks and tea. Joe was nice and polite and after waiting an hour he noticed me getting antsy and put me in a loaner to be on my way.
I am already considering an SUV to replace my wifes vehicle and I am looking at their inventory as I type this as this was an experience I was very happy with.
