We're working on a system to add cars that are out-of-bounds that we currently list. Check back in a day or so, but you should be able to specify the correct year.
Could you add an "out-of-bounds" (User Defined option) for Motorcycles. This will allow the users to enter in all fields instead of having Drop Down boxes. Then you could collect this data to populate future Drop Down list.
It's a big ask for a new site to make it impossible for people to sign up, and hope that they'll still be interested enough to try again in a few days.
I would be interested in an update as well. I have been waiting @ 1.5 weeks to add my 2009 Nissan Versa S....The 2007 and 2008 are there, but there is no option for the 2009.
