I bought my Nissan 350z from Ron Tonkin Honda in September of 2008- The dealership went above and beyond to make the deal work, including getting me an awesome interest rate, and driving over 90 miles one way to have my parents sign off of my previous loan for my trade-in. All I had to do was find something I loved, negotiate, and sign. It truly was painless, and they put me in a car I didn't think was do-able for me due to my credit and my trade-in value. I even thought I would have to go to get a new trip permit when my plates hadn't arrived, but got a trip permit in the mail from them.
Fast forward 2 years when I'm ready to buy a family car, different salesperson, same great treatment.. no pressure, I looked at everything and kept everyone at the dealership until midnight again, no complaints from them (afterall, they were selling me a car!).. they negotiated a price I could afford including a great warranty, and off I drove. I honestly won't go anywhere else to buy a car again- these guys are GREAT!! 2 years later the people in the sales department even remembered me :)
Pros: no pressure
Cons: none that I can think of
