Cordite,
You have some good ideas.
I agree with this:
A Honda section, Toyota section, Nissan section because they are very busy.
I agree with this:
Combine Mazda, Mitsubishi, Subaru, Nissan, and Toyota, together under
"Japanese" Import tech.
I agree with this:
A new Events section with subsections for TR Events, Local Events and Track Events.
Otherwise the rest exactly as you suggested.-Bob
