Background
The 1971-1989 Mercedes SL, the R107, was an enormously hard act to follow. It sold strongly across Europe and especially America, never seeming to age very much, and it reinforced the Mercedes reputation for first-class luxury embedded in bank-vault build quality. Where do you go from there?
The answer is that you commit four years of development and hundreds of millions of Deutschmarks to getting it right. You build in more technology - most notably a long overdue powered soft-top, but also a multi-link rear axle, optional electronically controlled damping and most impressive of all, a rollover bar that erects in a split-second in the event of an accident.
Just piling on the technology doesn’t count for much if the durability isn’t there, though. But this was Mercedes in the days when the range and the output was small enough to keep quality control tightly in hand. The R129, as this model is known, is really the last SL with that old bulletproof build quality.
Its production life didn’t quite match the 18 years of its predecessor but it managed 12 years, finishing in 2001 after a subtle but successful facelift in the 1996 model year that kept the car looking current and included better gearboxes and side airbags. The range of engines was always impressive, from 2.8-litre sixes to muscular V8s and opulent V12s, topping out with the frankly bonkers 7.3-litre AMG unit.
But where are values going now? Surely the R129 is going to follow the trend set by the R107. An everyday sight for years, their time as classics has finally come and the good ones have shot up. The same, it seems, will soon be true for the R129.
