That original 135i M Sport Coupe, to use its full name, was forgotten the very moment the later car was launched and overshadowed entirely by the thumping 1M. In fact, even I, someone who was once pretty damn sure he'd own a 135i at some point, had forgotten the thing ever existed. It was based on the original 1 Series - the one with the slightly surprised-looking headlights - rather than the second generation 1 Series, which spawned the M135i. It was also only ever sold as a two-door coupe or cabriolet, not a three- or five-door hatch.
I was only reminded of the pugnacious little coop when reading about the forthcoming M2 CS earlier this week. That's a car to look forward to. If it does for the M2 what the CS upgrade did for the M4 - namely, give it the body control it always should have had - it'll be a truly brilliant performance car. But if it sells for anything less than £60,000 I'll be amazed.
Is the 135i a looker? Not really. It appears a little bit anaemic around the arches in photos, as though it needs a ruddy good feeding, but in the metal, it's actually more attractive. The stubby, rear-wheel drive proportions are at least quite suggestive.
It used the twin-turbo N55 straight six, the one that featured a pair of relatively small blowers to give good response at low revs. The puny M135i only had a single turbo. Rubbish. Peak power was 306hp, which always felt very punchy in what was actually a very small car. (The last few 135is actually switched to the single-turbo N55 engine).
Completely outshone by a younger sibling. Poor 135i. It's the Jamie Murray of the car world. Mind you, which racket-wielding Scot lasted longer at Wimbledon this year?
