Tell this bozo to go drive an E55 or a C32 if any Benz dealer will possibly let him. Or better yet, an SLK32. 349 horsepower in a tiny roadster could change his tune real fast.

Besides, a Kia Optima V-6 has manumatic shifting; I drove one recently. It's not THAT special! BMW doesn't have a lock on that; Mercedes has tiptronic shifting on pretty much every model these days.
