Do NOT go to these crooks!!!!! I have had nothing but bad experiences with these people. Originally bought my car from them in April '11, and had nothing but horrible experiences.
I see you are in South Jersey, a place near me that I like to use is Devon Hill BMW (30 minutes closer than otto's). You will need to make an appointment to get a car in advance (it's a free loaner), but the guys their are great and they take really good care of your car. Chris is my service adviser, he's a great guy.
Good luck, and stay away from otto's!!
