Great point Michael. Manfred von Brauchitsch in his Mercedes-Benz demolished the existing Donington lap record by 15 seconds in 1937, giving an idea of how much faster the German cars were than the local contingent. And for an entrant to be classified a finisher, they had to finish within 15 minutes of the winner after the 3 hour duration, which none of the British teams managed. So maybe Murray has a point in that the race itself was somewhat boring, especially as several of the German cars failed. But from everything I've read, the sheer noise, speed and smell of the M-Bs and Auto-Unions made for such a spectacle, the actual racing itself played a secondary role.
