I have been driving both a MB 350 E and a Infiniti 35Mx for the last 3 years. I have now left the E mostly for my wife for the 50,000 miles that I have put on the Infiniti in last 3 years have been some of the best driving I have done. Granted I am 60+ and may keep an egg between my foot and the accelerator, however, I do that for both the cars. In my opinion Infiniti M is a much better designed and built vehicle for which I paid approximately 8% less than a comparably equipped 350 E with all wheel drive.
