Background
The Mercedes-Benz R129 SL was built between 1989 and 2002, a production run of more than a decade that eventually saw more than 200,000 examples being built. Replacing the much-loved - and even longer-lived R107 – this was the car that probably did more than any other in creating the hewn-from-solid reputation the company enjoyed at the time.
Using a shortened W124 floorpan, the R129 was technologically advanced for its time, featuring electronically controlled suspension damping, a hydraulic roof mechanism, and a hidden rollover bar that could erect itself in milliseconds if it detected a less than optimal situation was developing.
Only ever available as a two-door convertible, the SL was nonetheless offered with a decent range of engines whose capacity still bore a direct relevance to the model designation, a logical system that even idiot motoring journalists and discerning consumers alike could understand at a glance.
So, even a dolt like me could work out that the SL280, the baby of the range, was fitted with a 2.8-litre engine and the top-of-the-range SL600 had a six-litre V12 under the bonnet. In between were the SL300, SL320, and SL500. I’ll leave you to work out those engine sizes for yourselves.
The subject of constant revisions throughout its life, the SL range ensured there was a car for all budgets and moods, from a straight-six with 190bhp and a manual gearbox all the way to the mighty V12 with 389bhp and more computing power than was required to put man on the moon.
With a minimum kerbweight of 1800kgs, the SL was always more of a grand touring car than a lithe, agile sportscar but it crushed continents with the same disdain it shrugs off the years; few secondhand convertibles make more sense than this, making the R129 a great buy for the canny enthusiast with an eye to gentle, reliable, and yet very stylish classic car motoring.
NB: cars up to 1993 were referred to as the ***SL, while cars after that time had the model designation reversed, with the letters coming before the numbers. Not a lot of people know that…
