Your car isn't just transportation. It's an avatar; an outfit that sends a message to everyone around you. When that avatar is a Rolls-Royce, you're an instant celebrity. And when that Rolls-Royce is a convertible, you're very much on display. On this episode of Ignition presented by Tire Rack, MOTOR TREND's Senior Features Editor Jason Cammisa takes a Dawn to the beach to tell us what's so special about this car. What does nearly $400,000 get you? Is this just a rebodied BMW 7-Series? The Dawn is, after all, based on the big Bimmer. And more importantly, does the big, twin-turbocharged V-12 let you do burnouts? Is that even important? And though the Dawn is a convertible version of the Wraith, does it feel any more special?
