Amazing comfort without sacrificing performance.

My m56 is reliable, handles well in snow, and has plenty of power. The interior comfort is amazing - includes heated steering wheel and heated/cooled seats. Great sound system as well. I have had a few small issues with the engine but they were quickly resolved by my local dealership. Also one thing to note is that if you have a flat tire on a car with all wheel drive - you need to replace all 4 tires - which can be expensive if you are not ready to replace all the tires.

2011 Infiniti m56 is a great clean smooth riding car! Great for all age groups.

It is a wonderful car and has been super great! The only reason I counted off a star is because it is not the best gas mileage in the world but it still is pretty decent for such a great car. If I had to buy another car it would for sure be an Infiniti. The car looks so clean and fancy but does not take a big chunk out of your wallet to afford one. The car drives super good and I have had very few mechanical issues with it just the normal oil changes and having to get new tires once since I had it. I definitely recommend this car for any car buyer it is great for all ages!
