Most examples had the 3.9 litre V8 engine and five-speed manual gearbox. Most elements of the CSK's specification were drawn from the four-door Vogue SE or from US-market models. Each car has a individually numbered plaque on the radio panel confirming its exclusivity, discreetly bears his insignia, and in 1990 cost ?28,995 (manual). For an automatic you had to pay ?30,319.32. The Range Rover CSK features a number of modifications improving both performance and passenger comfort. It's the fastest production Range Rover ever built at that time, with the proven and a re-chipped version of the 3.9 litre V8 engine developing 185bhp. The increase in performance is complemented by improved handling at high speeds. Land Rover UK had introduced front and rear anti-roll bars and sports dampers, to give a smoother, more comfortable ride for on-road handling. The roll stiffness is increased by 25 per cent over the standard production model. This all gives remarkably positive and responsive driving.
