I don't think they're terrible, but the interior certainly wasn't very European in aesthetic. Crucially, it was actually longer than the equivalent Mondeo estate, so that says a lot about its origins for the US market where size is prefered.
I think it's a meh. They look OK to my eyes out on the road and when they haven't been modified there's nothing shouty about it. A clean black example could almost convey classy. They drive well too and I prefer that to its cool factor.
