Manuel plzzz shhhhhhhhhhhhhhhhhhhhh.
You can actually do a search in this forum to find a lot of discussions about this topic....
My humble opinion is that if you are going to buy a M-powered Sports-Car, then let it be a true sports car and get a manual, so you can get the most power/performance/fun out of it. If you just want to get an expensive and very comfortable car, that is gonna turn a lot of heads then I would recommend a Benz, or 7-th series...
P.S. M5 is one of my dream-cars.....
