Somewhere, in a pile of old '70's BMW bulletins I have the info on the driveback where UK dealers who ordered one could drive the car back to the UK. I'll have to look for it. I had an Inka orange one that was such a car, one of Park Lane's iirc, 1972on the 'L'.
The late Bill Body Editor of the once great Motor Sport magazine and Michael Tee his production manager did an epic Ten Capitals blast in November 1972 in this Golf Yellow CSL. They drove this car very hard, but it never missed a beat.
