Jason, remeber this is for the Nissan Xterra Championships, a physical endurance/race/other phisical activities event. Nissan wanted their vehicle (the Xetrra) to be showcased during the event to promote the races and for marketing purposes.

In the past it has been an Xterra ONLY event and this year I asked if other nissans could come, but not be entered into the show and shine contest. So you are more than welcome to come show your truck (without being in the contest) and hang out with us (free give aways, lunch and off-roading with nissan), but please understand that this was originally an Xterra only event as it pretained to the Xterra Championships.
