New Label and Navigation Structure for Site

I recently got some very good feedback from one of our readers who found it a bit hard to navigate the site and find the info that he was looking for. By listening to his feedback, I realized that over time, as the number of posts has grown, my early approach of labeling each post with all the manufacturers and countries/service branches which were mentioned within the post no longer made much sense. So now, instead of over-using the labels, I have created a series of 'index' pages that serve as an intermediate step in the navigation to the actual content.Take a look at it and let me know what you think, particualrly if you have suggestions for how to improve things further. It is your valuable feedback which is helping to make this a better site!
