There is a reason why I hate mbworld.
They behave like a honda board. Think so godly about their car.
I still have 04 E55, bought new in 2003. Stock to Stock, the E55 will pull about 1/2 to 3/4 length on E60 if launched from dead stop. But north of 80 miles, E60 will walk away from E55 like E55 is stationary.
F10 on the other hand will pull on E55 through out the speed range. Even 6MT will be faster at launch. If anyone is down to show some smack, I can provide both cars.
