I know a young lad who's just passed his test,his family are very well off and bought him a brand new a3. He got pulled by the law asking him all kinds of stuff like how can you afford this, is it yours etc. He was polite and what not, old bill still not happy, wrote him a ticket for not having any screen wash in the bottle !
