The long version

Half the ownership experience happens before the first drive; plenty of these arrive as a kit and get bolted together in a garage over a winter, which filters out anyone who wanted a car rather than a project. Club racing absorbs a huge share of the fleet, and the modest, steady value climb since 2015 looks nothing like the speculative charts elsewhere in this index; nobody is flipping a Seven for auction money. Smiles per Dollar and Track Rat are self-explanatory; Endangered Stick just confirms Caterham never considered building it any other way. Ask any owner what keeps the car parked, and the answer is never resale.
