Spares or Repairs This Smart Car ran wonderfully without any MOT observations. The mechanic I used replaced the rear drive shaft (I think that what it's called) and after that it would run in the dry but not when it got wet. I've replace the gear change controller twice and that hasn't made a difference. It's now a none runner and will not start. So looking for a good home. You'll need to bring a car carrier or tow it.
