Full Description: Sport-focused, intelligently designed and attractively priced, the 2009 Infiniti G37 is an excellent choice for an entry-level luxury sport sedan, coupe or convertible.Unification is a wonderful thing. In terms of Infiniti's G37, it applies not only to the union of coupe, sedan and convertible models but also to the line's harmonious blending of performance and luxury. Last year's coupe became the first to wear the G37 badge, owing to its larger and more powerful 3.7-liter V6 engine; the sedan model, however, retained the G35 name, in keeping with its carry-over 3.5-liter V6. Now, with the 2009 sedan also gaining the larger engine and a convertible joining the stable, the lineup is unified under the G37 banner.Thanks to the ideal weight distribution provided by Nissan's second-generation FM platform, not to mention that brawny V6 power plant, the 2009 Infiniti G37 has performance entrenched in its bloodlines. But the G37 is about far more than just going fast -- it also boasts an attractive cabin, a plethora of high-tech features and a suspension that's supple enough for the daily commute. The G37 is further enhanced this year by a new seven-speed automatic transmission, which promises slightly better fuel economy and acceleration than last year's five-speed.In a nod to modern trends, the new G37 convertible has a retractable hardtop that flips, folds and stows beneath the trunk lid in less than 30 seconds. Infiniti prides itself on having to add just a quarter-inch to the overall length of the G37 coupe in order to create the convertible. Several convertible-specific features are offered, including standard pop-up roll bars and the Bose Open Air sound system with headrest-mounted speakers. Increased structural bracing reduces body shimmies to just an occasional subtle waggle in the lower cabin when traversing pavement buckles, but the convertible ends up weighing about 450 pounds more than the coupe.V6 3.7 Liter,Automatic 7-Spd w/Overdrive & Manual Mode,RWD,Technology Pkg,Traction Control,Vehicle Dynamic Control,ABS (4-Wheel),Anti-Theft System,Keyless Entry,Keyless Start,Air Conditioning,Power Windows,Power Door Locks,Cruise Control,Power Steering,Tilt & Telescoping Wheel,AM/FM Stereo,CD/MP3 (Multi Disc),Bose Premium Sound,Navigation System,Bluetooth Wireless,Parking Sensors,Backup Camera,Dual Air Bags,Side Air Bags,F&R Head Curtain Air Bags,Heated Seats,Cooled Seats,Dual Power Seats,Leather,Power Hard Top,Bi-HID Headlights,Premium Wheels 19+,Sport Pkg,
