I bought my 2012 custom from Earnhardt in Gilbert/Mesa and it was a decent experience. However, I went to tradei that jeep to them a week ago and they low-balled me on my trade and seemed indifferent about selling me a vehicle in general.
However, I went to Moore in Peoria this week and I have to second what everyone else has said. It was a great experience, and I was treated really well (and got a great deal). I have the dual top option (had my soft top on) and they came to Chandler to pick it up the next day. Two resounding thumbs up! Oh and they offered by 4k more than the other place on my trade.
