At day's end, I don't worry about it. If I can drive a 32-year-old mostly-always filthy RS-look Carrera down Rodeo Drive in Beverly Hills, and turn not just the heads of the new Porsche, but Ferrari and Lambo set, then any of us can.
Many people know well-kept classics when they see them. My favorite is the eighty-year-old couple who stopped to appreciatively ogle my car, lingering to the point that I thought the old man (or woman) might try to steal my car...
For my money, Boxster and 996 owners - even GT-3 owners - lack something we have in abundance - real 911s blessed by Ferry's design; cars which will never again be reproduced as they are.
That says something no matter who is driving what...
