Mercedes CLK GTR

Even taking into account that the CLK GTR was a road-going homologation special (differing only slightly from the pure FIA GT Championship car it was based around) it was still a pretty unpleasant car. The cockpit was a cramped place to work, and although the GTR was fast, with 6.9 litres of AMG V12 giving 199mph, the recalcitrant sequential gearbox was reluctant to change up and too often the handling seemed poised on the point of snap oversteer, so it was hardly a relaxing drive. Although minimal efforts were made to civilise the car in an attempt to keep the price down, the £1.1m CLK GTR, of which 25 were built, was still listed by Guinness as the world’s most expensive production car.
