I purchased my 07 MCS at Irvine MINI. They had the right options already on my car on the lot. They have a good selection of old and new ones in the back and were really easy to work with. I suggest seeing Alex (girl) for the MA. She worked with me well and was easy to get along with. My wife also purchased her 07 Cooper a week later from the same place and through Alex as well. Some say Irvine is horrible but I have had both good and bad experiences there. Same for Crevier. Totally depends on who you deal with and how you carry yourself to be honest.
