What BRitish company manufactured an alternative to the Caterham 21?
Lotus Elise The Lotus Elise is a two-seat, rear-wheel drive, mid-engined roadster conceived in early 1994 and released in September 1996 by the British manufacturer Lotus Cars. The car has a hand-finished fibreglass body shell atop its bonded extruded aluminium chassis that provides a rigid platform for the suspension, while keeping weight and production costs to a minimum. The roadster is capable of speeds up to 240 km/h . The Elise was named after Elisa, the granddaughter of Romano Artioli who was chairman of Lotus and Bugatti at the time of the car's launch.
Reliant Regal The Reliant Regal was a small three-wheeled car manufactured from 1953 until 1973 by the Reliant Motor Company in Tamworth, England, replacing the earlier Reliant Regent three-wheeled cyclecar van. As a three-wheeled vehicle having a lightweight (under 7 cwt, 355.6 kg) construction, under UK law it is considered a "tricycle" and can be driven on a full (class A) motorcycle licence. A light-commercial version with a side-hinged rear door was marketed as the Reliant Supervan.
