 I researched and drove the Mercedes E500 and the BMW 530xi before I drove this car. I went right back to the showroom and bought it - never looked back at the MB or BMW. The ride, power, handling, and technology in this car is head and shoulders above them. I get compliments from people that see this car at night! A real head turner. I love the MMI. The power in this 4.2 reminds me of my 2001 Corvette - this car may keep the Vette sitting in the garage under it's cover.
