I recently traded both my 06 Infiniti M35 Sport 5A and my 08 Nissan 350z 6M for the 09 Infiniti G37 Sport 6MT with Premium package, mats, illuminated sill plates, mudguards. For less than $38,000 I got the best of my M35 Infiniti style, power and refinement and the raw power of my 350z. with 2+2 seating and a useable trunk. The handling is precise and controlled, the power sport seat adjusts back, thigh and leg bolsters for a precise fit. The 6 speed manual is short and precise. Averaging over 20 mpg during break in.
If you are thinking BMW 3 series or Audi A5 coupe, the G37 Sport belongs on your shopping list!
