As far as the cars go, the "VIP Pack" grants 5 of the world's fastest and least pronounceable cars, including the Lamborghini Gallardo LP570-4 Superleggera and the Bugatti Veyron Super Sport. Your garage will also come stocked with 10 of history's "best classic American muscle cars," although those vehicles have yet to be specifically named. You'll also land the previously announced "Ship Bonus" pack, as well as an unknown number of customized BMW whips that will also be available as day-one DLC.
Cars of Forza Motorsport 4 Presented by Top Gear is a 96-page gallery of auto-erotica, highlighting the game's many vehicles via images from Top Gear's "extensive" collection and color commentary from the publication's editors. This mirror's the game's Autovista mode, where Top Gear's Jeremy Clarkson says (presumably) hilarious and British things about cars. No pricing information has been given, but we assume it'll probably still be cheaper than buying an actual Koenigsegg.
