They didn't say how many prototypes were made, three at least for development, not counting the ones built on kit car chassis, not counting the three for the 100th anniversary. Anyway this one is going to come with a device to limit its top speed to 5 mph. If that's a chip, can't that be changed in seconds? I wonder if the DMV computer in whatever state the buyer lives will kick it back saying "that model didn't exist in 2004." of course if it's bought as a race car, won't make any difference.
