...which is to put them together on the Nurburgring, apparently.
To be honest, we weren't too sure about posting this video, being as articles involving the words 'Nurburgring' and 'BMW 1-series M' tend to inspire what we shall politely call lively debate on the PH forums, but we like a good forum scrap as much as the next chap, so we couldn't resist.
Of course, in reality this video settles nothing: the track is full of slower (and faster) cars, we have no way of knowing which of the drivers is faster, and we can't even be sure whether they're both really trying hard. And anyway the 'official' 'Ring times for the M3 CSL and 1M are 7m50s and 8m15s respectively, so the 1M shouldn't really be getting a look in.
Still, we suppose it makes a moderately amusing way to solve an unsolvable argument...
