Well now we HAVE to have some standards!
Mustang is BORDER LINE "sports car" at best. GTO? Fuh get about it.
2 passenger only? Nah, 4 place is OK. Like the Austin Healey 3000 is "four place". SO, the sports car criteria would have to be a certain cubic feet of interior space, overall car weight and two worthless back seats will still let you "in"! !
McClaren F1, Lambo, Ferrari as sports cars? Hmmmm,,,,,they might be "exoctics", a different category!
Oh man,,,,somebody let that heavy weight Vette in, it aint right I tell you! Niether sports car nor exotic....wait,,,,, the 1953 model would have to be "sports car". 1963? To heavy to qualify?
Whew,,,it is complex!
