Why are so many great sports cars built in Italy and not, for example, in Spain?
I think that this question is based on false presumptions. Here is a list of great sports cars from places other than Italy, right off the top of my head: Saleen S7, Ford GT40 (US) TVR, Aston Martin, certain Jaguars (Britain) Porsche, certain Mercedes and BMWs (Germany) Acura NSX, (Japan) Last I checked, the Bugatti Veyron wasn’y Italian either. For sports/performance cars without the huge price tags, there are the Nissan Skyline GT-R V-Spec, Subaru WRX STi, Mitsubishi Lancer Evolution, Seat Leon Cupra R (Spanish!)… all of which are considered sports cars, at least in Europe and Asia. Heck, overseas, they got some non-Italian sports cars you never heard of!
