The two sets with the F430 and the McLaren F1 are excellent, especially the sunset shots which are really beautiful (and the close ones even more !).
The BMW set is beautiful and the two "shapes" shots are especially really splendid.
And that last bunch of photo is full of great shots : love the angle, toning and lightning in both the Skyline and the Huayra one, and excellent atmosphere in the Fiats one.
