If you asked a young kid in the late 1970's what he wanted for his birthday, he almost certainly would have said the Panther Six. With its six-wheel layout and twin-turbo 8.2-litre Cadillac V8 hung out back, it looked like a car from the future. Claiming a top speed of 200mph, only one black model and one white model were ever made. One car is known to be in the Middle East somewhere and the other was shown a few years ago at the 2008 NEC Classic Car Show.
