I tried to change my order to Msport about 3 weeks after I placed it. I really didn't give it much thought when I ordered because I was ok with either the Msport or SAP. But when I thought about how much I was spending on the X3, I said why not upgrade. I would have got the carbon black too. My status was still in "order proceess' at the time but was told I wouldn't be able to change. I suppose I could have escalated it up the chain but it wasn't worth it. I could use that extra money to buy snow tires and wheels. I'm waiting for the 2 door version of the X4
