I am currently in the market for a new Sports Sedan. I know the three fastest sedans are the E55 AMG, M5, and the XJR. I have
already ruled out the XJR since i used to own a Jaguar and had horrible experiences.

So now its pretty much down to the E55 or M5. Both of these sedans are so similar in performance that it is really hard for me to
decide.

I know the M5 has an awesome 6 speed manual but on the other hand, the AMG has an awesome driver adaptive automatic. To tell
you the truth, i really have no preference when it comes down to the transmission.

Both cars look amazing plus they are both so exclusive. Also, i have been reading some of the posts on www.bmwm5.com, and it
really seems to me that the M5 has quite a bit of problems. Is that normal for BMW's? I have owned neither Merc or a BMW but i
have heard only great things of both cars.

I understand this is a BMW forum, but if you could please try to be as unbiased as possible in your responses it would be greatly
appreciated.

Once again, i want to thank you guys for providing such a useful and informative board.

PS. Before any of you start criticizing me for being a non-enthusiast since i have no preference to the transmission (like the people on the M5 board), please understand that i do not consider the E55 or M5 a sports car. I am just looking for the best sports sedan to complement my stable of a '00 Jeep Grand Cherokee Limited V8, 993 Porsche TT, and my F355 Spyder (360 Modena on the way!!).

Thank you, i really appreciate your opinions.
