Am I alone in thinking that seat swaps are some of the funnest motorsport-related videos to watch? In this clip, BMW Motorsport got together 2012 DTM champ Bruno Spengler and 1989 DTM champ Roberto Ravagila with their pair of M3s for a little fun at Hockenheim.

The whole thing is pretty interesting, but the sound of the E30 alone makes this video worth a watch!
