I remember riding in a few Citroën XM taxis in Germany (or was it Spain?) as a young fellow. I couldn't keep my eyes off them; looked completely different then anything I had ever seen before. Granted, now that I'm familiar with its predecessors, the XM looks like nothing in my book.

Yet, when compared to the god awful C6, the XM looks like the DS-21.

Are you sure that you're referring to the SM, not the CM? Never heard of a CM.
