I too was disappointed Nissan wasn't at the Portland auto show. But I did go over to Toyota and cause some trouble, even told some people very interested in a Tacoma to look at the Nissan. I told them I love mine and I got it for alot less than the sticker that was on the Taco they were looking at.
That and at least my floormats aren't under a recall.
I went to the OKC show this past week and Nissan was not here either. I guess with the economy like it is they are cutting back on their promotional budget. Besides they have a few recalls going right now and may not want to face people who are having this issue although that did not stop Toyota from showing up with a large display.
