I'm not so sure I truly understand what is meant by a sport car these days, in the past I would have consideredt a 2 seater, but the likes of sporting Bentleys and Alvis came with 4 seats, with a manual gearbox, preferably (for me) an open roof. Then the era of hot hatches seem to blur the lines even further:-
As per WIKI:-
''A sports car is a type of automobile that is designed with an emphasis on dynamic performance, such as handling, acceleration, top speed, the thrill of driving, and racing capability.
Definitions of sports cars often relate to how the car design is optimised for dynamic performance, without any specific minimum requirements; both a Triumph Spitfire and Ferrari 488 Pista can be considered sports cars, despite vastly different levels of performance. Broader definitions of sports cars include cars "in which performance takes precedence over carrying capacity",or that emphasise the "thrill of driving" or are marketed "using the excitement of speed and the glamour of the (race)track" However, other people have more specific definitions, such as "must be a two-seater or a 2+2 seater" or a car with two seats only.''
Seems to me a Morgan is clearly a sports car, which today may have more creature comforts and be less raw in its nature, but its is designed to be light and relatively powerful car,with limited carrying capacity, focusing on the driving experience.
