can you upgrade the arms to look more ERM ......................
modern

The have wipers come supplied with a plastic adaptor on them to fit standard arms, you get used to it. I just took my original wiper arms off, gave them a rub down and paint with some smoooooth hamerite spray I had kicking about. Looks good, or perhaps better than they were would be more accurate

Although I think I heard somewhere that Lupo wipers fit the Corrado so perhaps it'd be worth a fiddle about with see if they'd fit the mk2??
Like your light travels faster than sound thing, made me chuckle...
