If it's not a 4matic, you have plenty of options. A good starting place is tirerack.com. Enter your car info, pick wheels, then you see just the wheels that fit. You can then select some of them and see how they look on your model. Even if you don't buy from them, it's a great resource, and they don't sell junk so you get a sense of brand names. They are also pretty helpful when you call with questions.
