The "Seven" name goes back decades, denoting lightweight British- built cars that often found their way into competitions like hillclimbs and rallyes. It was one of the first accessible "everyman" automobiles, like the Ford Model T or the Fiat Ballila. In 1959 the name was used for Sir Alec Issigonis' remarkable Mini, aptly capturing the spirit of the original "Sevens".
Despite the seller's protestations to the contrary, the price for a decades-old non runner is always negotiable. I'd show up with cash and trailer for the best price on this old club car.
