The ’90s was the era of the analog supercar. Most of them were naturally aspirated, most had manual transmissions, they were mostly rear-wheel drive, and no such thing as a double-clutch auto even existed in a road car.

Some Porsche enthusiasts still frown upon the front-engined four-cylinder Porsches of the ’80s and ’90s, but these cars are proper sports cars, despite not being the hallowed 911, and even though they don’t have a flat six-cylinder hanging out the back.
