I agree w/ you that the E55 is no sports car. I enjoy my M5 a lot although it is somewhat jerky now, but nothing beats the driving experience . The E55 has a lot of creature comforts, a lot more than the current M5 as well as the next generation I am sure. It's a lot easier to throw in a supercharger to get more power, but it takes a lot more time to develop a natraully aspirated engine w/ more power. I guess for some its just easier to take the easy road out? I can't elaborate much more on this tonight, im tired..
