: . . . So it could be that the Test department had just been testing that
: combination of electrics, rather than being anything
: experimental on the car. I imagine having an F1 driver test your
: road car is a pretty thorough test all round though! . . .

That could be . . . although --- using Siffert for testing electrics might be juuuuust a bit of over-kill

And still, there's this green 911 that keeps turning up. In paddocks. And on movie sets. License = FR 10032. 'FR' denotes 'Fribourg' --- Sifferts home-town . . . and apparently this was his personal plate

This photo was taken on a roadside in France, in the summer of 1970, during the filming of the movie 'Le Mans.' Siffert was supplying race cars to McQueen's Solar Production company, as well as driving them for the movie.

If this car is 1059, then whatever testing Siffert was doing . . . he apparently found opportunity for in France. ;)
