Congrats on the new car
Re servicing, M-A8 on here (aka Marcin) heartily recommends the Audi VW Centre in Harrow and I think he drives over from SE London, so i'll be trying them next (i'm in East Finchley) with my D2 S8.
I tried some other specialists in Camden and CRouch End and left with some very hefty bills, so hoping for a more pragmatic approach from these guys
Best of luck with the new motor
