A structural innovation,[3] following the pattern set in 1935 by GM's German subsidiary, was the Ten's integral (chassisless) construction.

[5] 1933 was the first year all GM vehicles were installed with optional vent windows which were initially called “No Draft Individually Controlled Ventilation” later renamed "Ventiplanes" which the patent application was filed on Nov. 28, 1932.

This meant that the more expensive coupé was heavier than the saloon and no faster, limiting its appeal although it fared better in some export markets.

However, with British consumers cash-strapped, and the market for small family cars of prewar design closely contested, Vauxhall withdrew their 10 in 1947.

The company did not have the presses needed for monocoque construction and put a 10-4 front end and mechanicals on their own chassis under their own body.
