I'd be inclined to just have the OZHONDA logo on the front pouch pocket and the web address in small letters at the top on the back, both with thick stiching.
i like your idea of having the car on the back, but for people who drive different cars they should be able to get a pic of that type of car, or maybe instead of your car on the back, we could get our number plate or our name on the back?
