I would have swapped it years ago, were it not such a nice thoroughly modern and reliable motor - electric everything. A gentleman's carriage
It's a BMW in all but name, all BMW components.
Going back to the start of this thread and the handbrake. I became the world expert on the 75's handbrake system problems, supplying hundreds of refurbished/ modified compensators, until I gave up due to health issues. I also had a few drop in for help to sort their handbrakes out over the years.
No one had managed to work out, why the cables appeared to be stretching - they weren't, but what wasn't obvious, was that the compensator was deforming. Lots of new cables bought and installed, with no improvements. That was until I compared a new compensator, to several used and abused ones. Owners and mechanics were having to heave so hard on the handbrake lever to get the brake to work, it was putting a not designed for load on the systems, deforming the compensator. All because having a drum only used for parking, the drum internal surface rusted and rust acts as a sort of lubricant. Used on the move, just a little, to keep it rust free - it all works a treat.
