I'll be honest.. I originally went in for the 3.0 Gasser.. but when I heard there was a diesel due in '08, I was tempted to wait.. I have a Mercedes E320 CDI (2005), and I LOVE IT.. It gets 40mpg on the highway, and does 0-60 in under 7 seconds... the torque is prodigious! The only think that sold me on the BMW now was the sound of that Gas hungry V8! The irresponsible American consumer in me took over and I HAD TO HAVE IT. Ideally I would have gotten the Diesel, and I'm sure it's a superb machine, but that V8 just suckered me in!
