In less than two week's time the doors will open to the press for the 63rd IAA Frankfurt Motor Show and there are plenty of new cars on display that should either excite or even appal us. For us, the run-up to this year's show has been extremely busy. Every day for last month or so car makers have been announcing new creations that they plan to display - and if they aren't telling us about them, someone else is. But what do you know of the past stars of Frankfurt, and of the show itself? If you think you know a fair bit then have a go at this motor show quiz. The normal 4Car rules apply - don't cheat. If we find out that you have been cheating, we insist that you tell someone about your transgression and hopefully, they'll award an appropriate punishment. That'll teach you, won't it? Good luck.
