Tiny versions of the cars based on Ghostbusters, Back to the Future, The Dukes of Hazzard, and Knight Rider are unlocked by completing various tasks in the new Big Surf Island content. It's all stuff Burnout junkies would be doing anyway. You're going to want to hit all 15 Mega Jumps, 45 Billboards, 75 Smashes, and complete all 24 Road Rules, so you might as well be rewarded, right?

Unlock Legendary cars (for free!) in Burnout Paradise: Big Surf Island [Joystiq]

After a year of driving around Paradise City, the prospect of new places to play is immensely inviting. The 45 new billboards and 75 new Smashes shouldn't take too long to complete, but the insane jumps and new areas to explore should keep players occupied long after they've earned their Island license.
