Another alternative is a Mercedes Benz W114 coupe (250CE or 280CE)
These cars have fuel injection (bosch D-jetronic) 4 wheel disc brakes, some have air conditioning, and independent rear suspension.
The M114E engine will make 170hp while the M110E will make 185hp.
You may (with a feather touch) get 22mpg

Lastly, ditch the 22mpg requirement and find a car that will do less miles but has been converted to LPG like a series 1 Jaguar XJ6 or a Mercedes Benz 280SEL
