My wife is driving a G37 which we both love.
When my jealousy finally got to be too much I scrapped my SUV for a 2013 M37.
My alternatives were the Lexus GS350 and the Audi A6.
These are both comfortable and excellent to drive.
What pushed the M37 to the top is the comfort, interior room and nearly perfect ergonomics in terms of controls, etc.
The car is a blast to drive, has more comfort and sophistication than the G37, but is smoother and quieter on the inside. I've had Lexus, Mercedes and BMW's, but I would easily trade any of them for my M37.
