Thanks. These shots are directly from the game, it's just a matter of getting the right photomode settings (0 brightness, 0 contrast, 80-90 exposure, and play with the rest). Uploading them to Flickr also helps a fair bit as well.
The BMW design is the "Art Car" design. You'll be able to see one on the store front if you search "BBTD". There's also a black and white version of the same design that looks pretty cool.
