3. Panther 6
The Panther 6 was introduced in 1977 at the Earls Court Motorfair, and it featured an 8.2-liter Cadillac V8 engine which generated 600 bhp. It was said that this supercar could reach 200 mph, but it was never seen going that fast. Besides being powerful, it had some luxurious elements to it such as several telephones and a TV inside the cabin. The starting price of this weird-looking model was £39,950.
