Caterham has introduced a new, premium version of its Seven model, called the CSR Twenty, which is reportedly the most expensive Seven ever made. The limited edition roadster is said to have a high price tag, with some outlets reporting it to cost around £80,000, while another suggests it may be around $100,000. The CSR Twenty appears to be a special anniversary model, with performance capabilities that include a 0-60 time of 3.8 seconds.
