I don't know how many people have visited my350z.com but it is one of the most organized message boards I have every visited and that is where these suggestions are basicly coming from.

Have a sub section in the for sale section just for cars.

in the gallery section they have sub sections for colors and then post seperated by colors, also a section for movies.

This one would take a lot of work but there is also a gallery page. It has just about every different type of wheel that you can think of broke out by company then model.

Forced induction section.
NO2 section

What I love is the how-to section that you have!
