And I guess the Brits should thank the Yanks, as I understand it's a Yank dealer M3W that has been loaned to S&S to run the new EU emissions testing regiment...
Wonder if it was as simple as that?

S&S "yep that looks right"
EU "ok then, you're good to go"
With Brexit, will the EU emission regs still apply in the UK I wonder?
Probably. Still need clean air! Especially in traffic in a M3W you notice what comes out of the car in front...
