The Infiniti-M series is the new benchmark in this class without a doubt. It takes all of the good qualites of the Lexus GS and BMW 5- Series and combines them into one complete package. The car is quick and handles well, and it feels like a real luxury car. The interior is beautifully finished and the exterior is very nice looking. This car has almost every feature someone could … possibly want. Infiniti has hit a grand-slam with this car.
