I keep seeing a Lotus on my journeys to and from work, and would like to know what it is. It's old enough to need a black/silver numberplate, BRG, has a long bonnet and round headlights like an E-type, and an open cockpit with cage like a Caterham. I've looked on a couple of Lotusography sites, but haven't found it yet. I appreciate it's not much to go on, but any ideas?
