 This car is a nice car and very fun to drive. It's very fast with great mileage. I get about 26mpg around town and 33 or 34 on the highway. The engine is quiet along with the cabin but the exhaust is too numb for me compared to the Infiniti. The sport ride is way too stiff even without runflats. The only reasons I wanted the sport package was for thebetter seats, steering wheel and rims but the ride is just awful, especially in the winter when the roads get bad. It's too small on the inside for three people and a little too small for two people. It's difficult to get into because it's so low but the driving position is fantastic but the previous generation G35 was much better.
