Actually most of these newer luxury cars have blue tooth build right in so there is no reason for someone in a Mercedes/BMW/Porsche/Lexus to be talking on a cell without hands free.

I admit I DO talk on the phone while in the car, but it's always with hands free or the speaker phone.

I thought about getting a newer CPO BMW as I saw how nice my co-workers car was... but then I rode with him a few times and changed my mind. He was a totally different person behind the wheel. He even joked how he might as well live up to the "prick" standard owning a BMW came with.
