First - I love the Smart. It's a great choice to put a Mini in. I don't think I've seen any installs in the two seater version, but I thought I saw one in a four seat version. Go to the "Show Off Your Project" forum and search for 'Smart'. It may turn up.
Second, I like the graphics, particularly the dock on the back window. However, don't you think this is like advertising to thieves that you have a computer in the car?
