I love all 3 brands and have a great deal of respect for BMW and Benz. They paved the way for a company like Lexus. I am especially smitten with certain cars:
E30 M3
E46 M3 CSL
E34 M5
E 39 M5
Alpina B7 (I know I know)
Original AMG E class "Hammer"
AMG as a whole, I think they are superb
CLK DTM

Until recently, I thought Benz had the most beautiful lineup around. You have to love BMWs focus on sport then luxury.

Kudos to both!

 

BMW's have the best sports sedans around. Everytime I take a testdrive I say, "this is a fun car to drive, no doubt about it." I have no experience with Benz. I am going down to look at a the AMG C63 today though.
