2006 Nissan 350Z front

The Z gets a few upgrades on the inside, the outside, and under the hood, with the manual transmission version finally reaching a nice, round 300 horsepower. (The automatic continues with 287.) 18-inch wheels are now standard on all, and the still-too-crowded trim lines have shrunken from six to five now that the second-from-the-bottom "Performance" model got cleaned out.
