There is a nice shopping list in the August Top Gear magazine for speed week.
I picked one up today (happen to be in Swindon UK till I leave for Dublin tomorrow AM) and it is pretty nice write-up that takes up half of the magazine. M5, M6 Convert, C63 AMG Black, and MP4-12C included in the selection set.
Might consider laying hands on one if you have access to a Barnes & Noble (or similar) in the states.
