Not seen any over in the UK - sorry.
'course that might just mean that Sky are broadcasting it at 3am !!!!
Anyway on importing other forms of motorsport, I'm not an advocate.
I'd rather see the other tracks as well as the cars
There is a European V8 series already - I think loosely based on NASCAR and we built an oval for the series at Rockingham. I don't think it's a success.
Saw the European Supercars ( V6 IIRC ) at Knockhill and it would have been more interesting watching grannies in their scooters on an ice rink.
