Some manufacturers offer several material choices.
All convertible tops are made from some form of either vinyl or canvas. In general most post 1950 American cars and several European cars with removable convertible tops were originally supplied in vinyl. Canvas sometimes referred to mohair is used exclusively by Mercedes, BMW, Saab, and Porsche. Roll Royce and some Jaguar models use Everflex topping which is a variation of a vinyl topping. Yes, No and Maybe.
