First, I don't like "vehicle". it's not strictly a car and it's just a non-commercial word in my opinion. Second, "share" makes me think it is a car-sharing service, rather than a picture sharing service.
Then, unrequested advice for monetization!! I think you should let the users add the story of the car (There's the "car blog" button but I am not really sure how that works - maybe it's me, but it's not clear and you should make sure that the website is clear even to the dumbest of your readers).
Then, you might want to add a box "for sale Y/N" and if yes, the yes is clickable and you can then start an auction or put the two parts in contact... and get a little cut of the transaction.
The for sale option feature is currently in development, will hopefully launch next month!!
Yes car fanatics like all kind of cars, but you might create better, tighter communities if you selected one (and eventually replicate) niches: modders/racers could have some car porn to look at, antiques/american classics too but are very different than the fast&furious crowd...
It would help you get a better identity (just my 2 cents)
Anyone else producing a simple car gallery site or classic cars?
I'm emailing as many car clubs as possible to try and gain users, currently only a very small % of users are adding cars, any comments on the signup / add car functionality? If ur friend uses the site I would really appreciate his/her feedback
As for competition there are some car galleries out there but none focus on user generated content / car profiles, at most users can send pics in by email ( very lame! )
Thx again!!
