 The 6MT G35 coupe has the perfect balance of luxury and performance.  You can easily cruise around the city with the quietness and quality feel of luxury with a nice low hum of the exhaust reminding you that there is an animal inside when pushed.  The car is smooth but can be rough at times (sport- tuned suspension and 19" rims) but I love the feel of the road, I feel so connected.  The engine response is immediate and braking is superb.  Handling is on par with the best in its class.  Don't expect this car to have the luxury feel of a Lexus (interior- wise and quiet) it wasn't design that way and Infiniti did a great job balancing both performance and luxury. It's all about the experience.
