Background
The R129 iteration of Mercedes Benz’s highly regarded SL line of sports cars arrived with much fanfare in 1989. It’s predecessor, the R107, had reigned supreme as the ultimate automotive status symbol for almost 20 years but, by the late 1980’s, had become noticeably long in the tooth.
It was a tough act to follow alright but, luckily Mercedes Benz had thrown the kitchen sink as well as head design guru, Bruno Sacco, at the R129’s design phase. With the world teetering on the cusp of a computer-led technological revolution, the R129 was reassuringly packed to the gunwales with state-of-the-art electronic wizardry, each with its own confusing TLA (three letter acronym).
At the 1989 launch the R129 came in just three flavours. There was the 300SL, the 300SL-24 and the 500SL, ranging in power outputs from 188 to 326 bhp and in either inline six or V8 cylinder configurations. In 1992, however, the range-topping SL600 arrived touting a 6L V12 and upping the power ante to a meaty 393 bhp and an even more impressive 420 Ib-ft of torque.
The R129 successfully bought the SL lineage bang up to date in a way that seemed perfectly aligned with the dawning of the internet age and all that came with it. Bruno Sacco was to describe the R129 as his “finest ever car” and the sublime 6-litre, V12 example we have here is, surely, the ultimate expression of the breed.
