Been toying with the idea of a little footwell vent very similar to ones fitted to the early XK Jags. Little square metal box that sits flush to weatherstriping the footwell side when closed, but when opened looks like a little scoup.Boss at work restores them and mentioned they are cheap to source, and work quite well on the Jags on a hot day, but then again we are talking a guy who is working on Jags..perhaps a relative term to him.
