XJK inspired me to upload this red Honda S2000 pic after he noticed the unique roofline in this Lotus Seven pic: [link] When I saw it screaming around Laguna Seca I couldn't really tell if it is some unique fastback design hardtop installed on a typical S2000 convertible or if it is an actual coupe (either factory produced or custom-made).
