The third generation SL (R107) was launched in 1971, and featured a two-door monocoque bodyshell with independent suspension all-round. The power-assisted steering was Daimler-Benz's own recirculating ball system. Braking was by discs at each corner - ventilated on the front. Over its 17-year reign, the R107 range was powered by six versions of Mercedes-Benz's silky smooth 90 degree V8. The sale car on offer is the most desirable model being the 500 SL. Having been with its current owner for 12 years the Mercedes displays 77,300 miles and has had just 4 previous keepers, the last of whom from 1991 to 2005. Offered with 22 old MOT certificates and a collection of invoices plus 2 sets of keys, this big Benz has just benefited from an oil and filter change. Offered with both hard and soft tops, it carries an MOT certificate into February 2018.
