Most vehicles in the Transformers: Autobots and in Transformers: Decepticons for the DS are unlocked by scanning certain vehicles. Some vehciles require getting wi-fi tokens to unlock, and, if you replay some of the beginning missions, and even later missions, you can scan random vehicles, and most of them will be usable vehicles after you successfully scan them. There is also one vehicle, Generation 1 Starscream, that can only be unlocked by going to a Target Store and downloading the Transformers Trailer on your DS. Doing so will automaticcaly give you G1 SS.
