I’m sure there are many classic car enthusiasts on this site, so I thought this could be interesting.

The idea is that someone posts a picture of a detail of a certain car and that others try and guess the marque, model and year (if relevant). After four wrong guesses there will be a second picture of the car posted, then after 3 more wrong guesses another one and so forth. The car can be anything with four or more wheels: F1s, sportscars, road cars, …

I will start with one of my favorites: http://i42.tinypic.com/2laar01.jpg

Only marque and model needed.
