We all are waiting, as I have done for decades, and my father before me, and his before the time of that imposter Karl Benz who stole Denbeigh's patents.
The new Pure-silent-motor Denbeigh Ultra will be shown at the next Earl's Court Motor Show. Regrettably the launch has been postponed due to events beyond the control of Denbeigh Pure-silent-motor Company, to wit, the recent destruction of Earl's Court Exhibition Centre to make way for numerous undistinguished flats.
Note: FWIW I once owned the 1968 Morgan Plus 8 that was displayed at Earl's Court. A long story.
