The TVR 450 SEAC is a sports car designed and built by TVR in a one-year only run.[1] It used the same body style as the 420 SEAC but was fibreglass compared with the Aramid Composite (Glassfibre and Kevlar) body of the 420 and the same chassis. The only difference was the engine which grew to 4,5 litres and about 325 bhp (242 kW) and 435 Nm torque. As a consequence though the 450 SEAC was even more expensive to build and buy than the already expensive 420 SEAC, so about 17 were made. Curiously, rumour has it that more SEAC's are on the road now than were manufactured in the first place, that is because many wedges were converted to 450 SEAC spec afterwards.
