We towed our smart on A-frame down from the Tunnel to an intermediate stop in south Belgium. (place called Ave-et-Auffe try saying it) On arrival would not start. Problem is clutch has 'exploded' taking the gearbox and starter motor with it. It is now in our local garage but probably be beyond economic repair. The only theory that has been advanced is that somehow it put itself into gear while being towed although ignition was off and the key removed. I suppose may be feasible given that clutch and gearbox are electrically controlled . Upshot is that we are now without our toad.
