I'll start with a few
-Block Island, Rhode Island. Lots of low level exotics like Maseratis and M5/M6s take the cruise to the island, plus one of the first homes you get to on the island has a Levante.
-Chesterfield Gardens St, London, UK. just gonna leave this here
-Tilney St/Audley St intersection, London, UK. For some reason exotics are always around this one little area and I have no idea why
-The Beverly Hills Hotel, Beverly Hills, California. The inner parking is flooded with exotics idk what else to say
-The Dorchester Hotel, London, UK and everywhere around it. Just...

On Jakarta, Indonesia:

- Fairgrounds SCBD. On daytime, exotics can be found here, even on weekdays.
- Plaza Indonesia (weekends)
- Plaza Senayan & Senayan City (weekends)
- Pantai Indah Kapuk (everytime on weekends)

We already have a forum for this:
