While I have only purchased one car in my lifespan, so far I had a great experience with the car dealership I purchased my little Ford Focus at. I actually bought my car over the phone, as I was buying a car before moving to the area.
I flew out before moving to Scottsdale, to look at apartments and sign the paperwork on my car. Dealing with Chapman was pleasant, and they stored my car for me for 2 months before I officially was living in the area, and I did not have to pay to keep it.
The dealership is also brand new inside and even the service station has good magazines and is less unpleasant to wait in than most service stations of car dealerships. If you are considering buying a Ford (I know, I know bring on the Ford "Fixed or Repaired Daily jokes) in the Phoenix area then I would definitely look here. I did not find anyone to be pushy or live up to the evil reputation car salesman have in my experience.
