I guess the best way to sum up this location is: unmemorable. There was an equal blend of good and bad. This review is based on experiences in 2008-9 before the Orchid Ln location opened up down the street from work so things may have improved since then.
The good is that I did get a pretty nice service adviser named Mike S who actually ended up buying the 2000 323i sedan I traded in for the CPO 2006 330i sedan I bought from this location later. It helps to know the correct location you need to get before you head down Camelback since the CPO is on the south side of the street and the service / new sales is on the north side (gotta love the neatly ruled streets of Phoenix, right? even the navigationally troubled like me don't get lost). The service adviser I got at a later date was okay, but he was kind of impersonal and I left feeling like I was just another face in the crowd to him. I still wonder what happened to Mike.
The sales experience was a mixed bag. Although I got a very sweet test drive in a spicy candy apple red 1994 but oh so overpriced M3 convertible to whet my appetite, I felt pressured and hustled in the sale of the sedan I did end up buying. I was unconvinced from the get-go because I was never a big fan of the E90 chassis. It's like a reverse mullet. Party in the front, all business in the back. The sales guy did a big show of acting like he was bargaining with his boss in the back but for all the time he spent gesturing and talking behind that plate glass window, I never did get a better price than what he initially offered and his big sales pitch was "just take the car!" Lame.
