Those with experience of Sevens always come back to the normally aspirated mid-level cars being the sweetest all-round balance though. That R300 I drove was a case in point, the 360R I took to Oulton its equivalent in the current range. For a period between these it was known as the Supersport R, and that's the one I've picked out. Not cheap at £32,000 but it comes with the cachet of official Caterham Selected provenance with a factory inspection and 12-month warranty. And a free track day. I'd be cashing that in on day of collection I think.
It is, I think, a nice balance between the classic appeal and track-focused fun, having desirable upgrades like the DeDion rear axle, limited-slip diff, widetrack front suspension and the lower floor. It's missing the optional six-speed gearbox but the 180hp 2.0-litre Duratec is torquey enough for that not to matter and there's enough power to mooch in a high gear but sufficient revs to really nail it to the redline when you're on it. The colour scheme is classy too, though I might be tempted to swap the seats for something racier and put the newer matte black lights and screen surround for a more contemporary look.
You can't guarantee every drive will be as evocative as some of those ones I recall so fondly. But there's no such thing as a boring one in a Caterham. And you're off to a racing start for creating some new and equally vivid memories.
