I think a Classifieds Forum similar to
www.rx7club.com would be most beneficial to seller and buyer.
You can't browse or post to the classifieds forum unless you're a registered user (would help to keep down the spam/scam posts).
You'd have separate sections for Vehicles for Sale, Parts for Sale, and Seller Feedback. The search function would make browsing through them a breeze.
My $.02
The current classifieds are irritating at best with cross-postings all over and items in the wrong sections. I've stopped browsing them because of this.
