Where is the transmission information (auto or manual) that was previously shown. As a manual driver I like see this. Also, why not list the engine size as well? This would allow users to see how size, power (and transmission type) effects economy. Isn't that what this site is for?
The whole filtering system is being heavily worked on in the week ahead as we switch the way we organize vehicles. As merc6 noted, you need to click on the Edit Vehicle link at the top of your car's profile to review and set the fields for your car's engine, transmission, etc.
Previously we had very high level engine classifications and we are currently working to provide more granular classification. Previously you could not filter by manual or automatic but we plan to offer this in the future.
