 After driving 8 BMW's in my life, I finally had to admit that the 5 series interior is just getting too cramped for 4 people to ride in comfortably.  I looked at the A6 and was SO impressed with the handling, the fit and finish and the power that I never even went back to the BMW dealer. I DID compare the car with the Lexus GS, but the road feel of the Lexus doesn't come close to that of the Audi. This car rocks!
