1964 Sunbeam Tiger
This car was created with the intention of competing with the Jaguar E-Type, so that should tell you something right there. If you're a little older or a huge Steve Carell fan, then you'd recognize this car from the "Get Smart" series and movie, as Maxwell Smart's main ride (be real, you might've seen it, but you didn't know what manufacturer).
The Tiger is a performance version of th Sunbeam Alpine, which had four cylinders compared to the Tiger's eight. The car was only produced from '64-'67. When Chrysler purchased Rootes Group, which built the Alpine, they could obviously not continue using the Ford engine that was in the Tiger. Thanks to the inability to fit their own V8s into the engine bay without major alterations, the car was sadly put down.
