Background
Many thought that the R107 SL would live on forever. Made from 1971 until 1989, it still looked good but lacked the latest in tech and safety equipment.
So, as all good things must come to an end, the R107 production line was laid to rest.
Ready and waiting in the wings however was an all-new version, the R129 in Mercedes speak. Bigger, brasher, bolder, this new model was also to have a long life, some 13 years.
The R129 was of course a two-door, two-seat convertible with an automated fabric roof, colour-matched tonneau cover and a detachable hardtop. This rather substantial item could be fitted over the stored fabric roof. It is definitely a two-person job to remove it.
The R129 was designed in 1984 and was finally shown to an expectant public at the Geneva Motor Show in March 1989. We can imagine the wealthy locals clamouring for a look at the car to be seen in that summer, and sales commenced just in time for early buyers.
The SL received much acclaim from the motoring press of the day and very nearly scooped the European Car of the Year crown. It lost out by a smidgen to the Citroen XM. Whilst we imagine most SLs are still going strong thanks to Mercedes-Benz’ top build quality, when did you last see and XM? Longevity was not on the judging criteria we guess.
The R129 was designed on a shortened floorpan of the W124 saloon and featured many innovative details for the first time. Amongst the most notable was the electronically controlled damping and the automatically extending roll-over bar.
Modern multilink suspension replaced the R107’s rather archaic semi trailing arms system, much improving both the car’s dynamics and ride quality.
Equipment count was high, as befitted the SL’s luxury status, so all cars came with electric power for the window, mirrors, seats and fabric convertible top.
The R129 SL also has the distinction of being the first passenger vehicle to have seat belts integrated into the seats, as opposed to being anchored to the floor, B-pillar or transmission tunnel. We bet you didn’t know that!
A now a little SL royal trivia for you….
In 1991 Diana, Princess of Wales sold her Jaguar XJS in order to lease a metallic red 500SL. In so doing, she became the first member of the royal family to use a foreign car. The horror!
This caused much controversy as it sparked a media storm as it questioned whether a member of the British royal family should drive a car not made in the UK. Media pressure eventually forced her to return the car to Mercedes-Benz in 1992.
If you fancy a peek at it, you will find it languishing in the Mercedes-Benz Museum.
