Pros: What do you like about 2009 Infiniti M?
Superb dynamic tyransitions in comfort and safety.
I enjoy the "idea" of driving the vehicle whenever I approach it.
Compliments by rear passengers reflecting their comfort.
Dynamic safety factors that support safe lane discipline, especially at higher speed on narrow twisting road like the Merritt Turnpike in CT and NY. Cons: How would you improve 2009 Infiniti M?
Better gas mileage. My previous 2004 Chevrolet Tahoe actually got better mileage.
Stronger heating and cooling of front seats.
4 way TV as in the E. Backup camera is not accurate enough in tight spaces.
Red warning area is premature, so you tend to ignore it at the risk of damage to the car's finish.
More intuitive verbal commands and more verbal feedback from the system to allow for improved error correction. 2009 Infiniti M Review:
