E63 / E64 6 Series (2004 - 2010)
The E63/E64 BMW 6 Series builds on BMW's sporty heritage with aggressive lines and an incredible motor to back the design up. Available in coupe and convertible trims with a standard 4.8 liter engine producing 360 horsepower and 360 lb-ft of torque, the 6-series is a popular choice that exceeds expectations.

misfires

my 2005 bmw 645 started out with a rough idle when the mornings were in the 40s and once car warmed up it was fine, one day it stayed in a rough idle and a great decrease in power, the feeling on running on 4 cylinders. i had codes read as mis fire on cylinders 1 thu 5 i changed all plugs, and I dont believe all 5 coils could go bad overnight, anyone had similar situation,

Sounds like a common case of intermediate levers. You can try raising the minimum valve lift (you need a BMW diag scanner). If that doesn't work, make sure the basics are ruled out before you get the levers replaced.... it can be pretty expensive
