What a 6.2L that barely puts the same power out at the smaller V8 of the new M3? How creative Mercedes?!?! Hence, why they are always putting SCs on all of their cars.
Plus, you can only get the typical slush box from them. Albeit one of the best slush boxes on the planer, but still, no options. Hence, they don't get what a driver's car and experience is all about at MB still. Just brute power and refinement with no options for drivers. And they charge a heck of a lot more for them.
BMW all the way, won't ever own a Mercedes personally.
