I STRONGLY considered the G37 before ordering my SS. Took it for a test drive, while the fit and finish of the car was very good, the car simply did not raise my blood pressure at all. In fact, I found it quite boring.
After 5k of spirited driving in the Camaro, I have no regrets. Yeah, the interior is not the strong point of the car, but then, it is not supposed to be.
It excels where it is supposed to.
