It would be great to see photos of all three gens showing front, back, sides, if not photos, a text description. I've owned my 07 for about 3 months now and I still have a hard time telling them apart. The 3rd gen is pretty easy, and I'm better with the 2nd vs 1st, but other than being able to say the 2nd is more angular I can't really say what the differences are.
