Some commentators attributed the C5's failure to problems with Sinclair's marketing strategy; only a year after the demise of Sinclair Vehicles, the Globe and Mail newspaper called it "one of the great marketing bombs of postwar British industry".[1] Andrew P. Marks of Paisley College of Technology criticised Sinclair's marketing strategy as confused; the C5 promotional brochure depicts it as a leisure vehicle, showing boys in C5s at a football pitch, women in C5s on a suburban road, and so on, while the text suggests that the C5 is a serious substitute for a car. He concludes that the C5 was poorly defined, appearing to be "trying to grasp at two different markets" but was unable to appeal to either, and so failed to take off.
