A forum game I saw from another site which seems interesting. Here's the rules:
Rules:
1. Guesses must include make, model, and either year or generation.
2. If correct guesser fails to post new photo within six hours of comfirmation, anyone may post a new picture.
3. No disattatched car parts are allowed; only cropped, shrunk, etc photos of whole vehicles are to be accepted for guessing.
4. Production vehicles only; no one-offs, tunes or concept vehicles.
5. Unless a guesser can produce the actual photo used by a poster, no one may post a new photo unless a guess is confirmed by the original poster
(You should also change the filename when posting to make it less easy

)
So I guess I'll just post an easy car at first:
