In 1911, Sheffield Simplex Motor Works opened commodious London showrooms at 20, Conduit Street, off Bond Street, where its models were displayed.
“Now that its many attractive features are made easy to view in London all the year round, instead of necessitating correspondence with Tinsley, we may expect the Sheffield-Simplex to secure a larger vogue among those to whom the best only appeals.”
Wilfred G. Aston, a motoring correspondent for The Tatler, was a big fan.
“The Sheffield-Simplex is a car with a very pronounced personality, and you must be a very pachydermatous lump if you don’t appreciate that fact after about five minutes’ running in one.”
Production of the Sheffield-Simplex car ended about 1920. Too expensive and perhaps a little old-fashioned after the First World War.
