Mercedes 300SL Gullwing Coupe.If you’re worried you won’t have anything to do over the holidays this year you can stop. From the looks of things, the release of Forza 3 should keep you busy well on through the new year and into 2010, when you can catch all the major releases that got delayed. Turn 10 released the full list of cars on its upcoming 2-disc racer, a list that boasts more than 400 cars from the last 50 years or so.

The oldest car, the legendary 1954 Mercedes 300SL Gullwing, is like a teaser to a great meal. All 400+ vehicles will be available with complete customization when the game launches on the 27th this month. You really do get a chance to drive almost anything in the game, from Asian imports to European classics, American Muscle to the Italian supercar, there’s something for everyone in a game that looks to expand Microsoft’s answer to the Gran Turismo franchise. You can see the full list of cars at the official Forza Motorsport website.
