I am 25 years old and I have both 2000 E55 and an 2000 M5. E55 is by no means an old man's car. Both cars are just AWESOME, with different personalities, if you want a sportier feel and stick shift go with M5. I like M5 interior much better. However E55 gets a lot more attention on the street. It is a tough choice for me to choose between two cars since both are incredible.
