2007 Nissan Frontier Crew Cab Nismo 4dr Crew Cab 4WD 5.0 ft. SB (4.0L 6cyl 5A)
Still happy after 1 year.
 Bought new to replace an '01 2wd Crew Cab SE which was a great truck. I was moving to the Midwest and wanted 4wd. Great advances since then, better in all aspects to the '01. Great motor with acceptable mileage for a truck. I get about 15-16 city, 21+ highway.  Some folks don't like the interior, but I don't mind the plastic. It's put together well, and easy to keep clean. Gauges/controls are clear/logically ordered. Sound quality of speakers is good. I primarily an iPod via the aux jack. There is an iPod interface on the 2008s.  Get that instead of the disc changer if you can. You might want to consider step rails as it's relatively high off the ground.
