f there's one criticism to be made of the XK8 convertible's styling, it's how the convertible top doesn't neatly stow within the bodywork when lowered. It looks like an afterthought, actually. This roof cover, or tonneau, neatly solves the problem and looks like an integral part of the car. Supplied in primer and ready to paint to match your car, the cover installs in minutes just as the Jaguar-supplied leather cover with Tenax fasteners at the front. (The rear tucks into the gutter under the trunk lid.) The two lightweight pieces are made of fiberglass and can be stored in the trunk or behind the front seats. Leatherette storage pouches are supplied.
