I found some great pics for Stevie's vehicles. Has a pic of the vehicle and a zoomed in and zoomed out picture of the map. plus a blurb about the car. pretty cool, i'm very impressed with this site : )

Also as a side note this site has the same thing for the flying rats, in case gamesradar wasn't doing it for you. I know I was wishing they had the maps when I tried to use it.
