So--hopefully tonight--we'll have that functioning (at least at a search level). Still actively developing this, but if you have any suggestions, please post them in this thread.
As a starting point, users will be able to search the cars we have in the database. Over the coming days/weeks I'm going to hope to get a bunch of new entries, and keep up with this. Eventually, I'd also like to enable users to add entries to the database.
So--take a peek, and please offer suggestions here in the forum. While I can't promise every new feature (and likely that my be limited by my expertise more than a desire to implement code changes)

As always, thanks for supporting SpriteSpot.
