"Exotic" is just a made up label no different than "supercar" or "hypercar", "sportscar" or "musclecar". None of them have any agreed upon definition which makes them pointless.
Where I live I see Ferrari, Lamborghini, every model Porsche (including 2 GT3 today), McLaren, etc. every day. I drive by the Lambo dealership on my way to & from work. So to me, none of them are "exotic".
