Sleek3

I believe that this is a 1956 to '58 Lotus Eleven, please help if you know differently. According to Wikipedia, 270 of these cars were built, with some if the '58s being unofficially reffered to as Lotus 13. "The Eleven was designed by Colin Chapman and fitted with a sleek body designed by aerodynamicist Frank Costin. Its top version, dubbed Le Mans, was generally fitted with a 1100 cc (67ci) Coventry Climax FWA engine and occasionally with a 1500 cc (92ci)[1] Coventry Climax FWB engine mounted in the front of a tubular space frame and featured a De Dion rear axle and Girling disc brakes. Fully loaded, the car weighed only about 1,000 lb (450 kg). Versions for a 1100 cc (67ci)[2] Climax engine (Club) and a 1172 cc (72ci)[2] Ford engine (Sport) were also produced; both featured a live rear axle and drum brakes. Several cars were fitted with alternative engines by their owners, these included Coventry Climax 1500cc (92ci) FWB and FPF and 1200 cc (73ci) FWE, Maserati 150S 1500cc (92ci), DKW 1000cc (61ci) SAAB 850cc (52ci) and 750cc (46ci) engines. There were two main body styles: one with a headrest and the other with no headrest, just two small fins. Some cars were later fitted with a closed body with gullwing doors to meet GT specifications."
My grateful thanks to for helping to identify this car.
Edit May 7th, 2014: It would seem that this is a 1956.
