I drove my 2004 G35 for almost ten years, and just love this car. In ten years, the only reason I visited any shop was for Oil Change, brake change or tire change... This car is as reliable as can be.
if you want a luxury sports coupe as a daily driver, this should definitely be one of your top choices, I drive the 6 speed manual transmission with Navi and Brembo brakes, I love the power this cars ...
