F1 2013's pre-order bonuses - a bunch of classic cars, and some even more classic tracks to race them on - have now been made available to all as DLC. You can, among others, pilot Nigel Mansell and David Coulthard's 1992 Williams, and the 1996 Ferrari of Michael Schumacher and Gerhard Berger. Full details about the DLC can be browsed over here.
