CELEBRITIES wear disguises to dodge the paparazzi. Isn’t that Brad Pitt under the tweed flat cap and shades? Mel Gibson behind the silly mustache? Mary-Kate and Ashley Olsen wearing cat whiskers?

The auto business, like Hollywood, has its own paparazzi, and the star cars wear their own disguises. So-called spy photographers like Brenda Priddy and Hans Lehmann use long telephoto lenses to capture images of the next Corvette or Porsche; the pictures are snapped up by car blogs and enthusiast magazines and carefully scrutinized by car-crazy readers.
