EA has released a truckload of download content for its latest street racer, Need for Speed: Carbon.
For 800 Microsoft points you can download the Collector's Edition Upgrade, which gives you 12 new tracks, 6 new Challenge series missions and 10 exclusive cars, including the 92' Nissan 240 SX, 07' Jaguar XK and 06' Camaro Concept. However, you apparently cannot use any of the new motors in the game's Career mode. Ho-hum.
Additionally, there are also a number of packages for the lazy that unlock various upgrades also accesible via normal gamplay. Priced at 400 points each, several download kits unlock various tuning and performance upgrades, or you can splash out on the lot of them for 800 Microsoft points.
Similarly, there are a number of body kit packages available for 300 points each, and the 1999 Nissan Skyline GT-R R34, 2004 Lamborghini Murcielago and 2006 Dodge Viper SRT-10 are all up for 80 points.
