I liked Mike Gammon's answer - put them behind the wheel. Last fall when I got my new E-34 I "insisted" that my brother-in-law drive it. He did and he was wowed. He said he had always thought my last car, and E-30, was a "cracker box" and couldn't understand why I drove it. He understands now (and he doesn't know the half of it!).
