GT-R's all over the place (lots of Asian people in my area and they love it. Also GTI's and Subaru STi's.)
Bentleys everywhere too (I don't even take pictures unless they're modified in some sort of way)
Plenty of Audi R8's.
Porsche 911 Turbos.
Maserati GranTurismos.
Most common Ferrari is the F430 or the 458.
Most common Lamborghini is surprisingly the Aventador.
A lot of people are saying the see Vipers a lot, but I barely ever see them at all.
Wish I saw more:

Ferrari 599's

If i went to holiday,because in my city there is no exotic,usually i see a aventador most

Tesla Model S, My next-door neighbors car. And I see a lot of Tesla's in general.
