There is no such thing as THE perfect sports car. However, all things considered, I do believe this is one of the (if not the) closest example/s to the definition.
Mid engined, naturally aspirated boxer 6 with plenty of power to be still fast in modern times, but also not so fast that you'll receive a speeding ticket by just touching the gas pedal. It also hits the perfect middle between being too modern and outdated, and is also not so dangerous like Porsche used to be in the past.
With modern tires this would still make a formidable and especially reliable fun car.
