Wish list for a new car site?

[oldtimerz]

This site is great, and its focus is FORUMS...
I am a long-time car enthusiast. I would also like to create a car site, that has another different focus.
I have ideas of course, but if anyone has any suggestions for what non-forum features would be worth putting together.
I am hoping to get the name vroom.ca

There are already many car sites on the web, so what would make it worthwhile for visitors?
