One thing to consider, scooters aren't so fast that you can avoid being seen by someone you know.
Can you still get those one piece white and blue cover-all things that they used to wear in all the scooter ads?
Oh, you won't have to worry about the mod image unless you add on about 50 mirrors. As it stands, it's just an economic commuter machine. If they ever start rationing petrol again, you'll have to get one of those big Daimler saloons with the pre-selector gearbox to go collect your stamps and use it as a storage tank for your scooter.
