Saw a dark silver A2 (forgot name of colour now!!!) in CMK, not to far from a major spanish banking HQ looked like it had non standard wheels (RS6 style maybe) I was in a rush so didnt get a good look.
I have just returned from two weeks hols and am catching up with life on the forum.
100% certain that your spot would be me shao_khan; venue and description match. If we pass again, give me a flash, perhaps we can pull over and put a face to the name!!
As a side issue - 2 weeks away and a staggering '725' new posts - the smallest Audi the A2 may be, but it has arguably the biggest following bar none!! Well done all!!
