Background
The R107 version of the Mercedes-Benz SL remained in continuous production for an incredible 18 years. The thinking behind it must have been, if you have got a great product that sells well to an informed and enthusiastic fanbase, why change it?
The car caused a sensation when it was launched in 1971. Clean simple lines, powerful engines and the legendary Mercedes build quality were undoubtedly a recipe for success.
The SL was more a grand tourer than an out and out sports car, but that’s not to say it was slow. The more powerful V8-engined cars were swift and could happily cruise the derestricted autobahns at three figure speeds for hours on end.
Manual and automatic gearboxes were offered, but most buyers preferred two pedal driving.
There was the option of a hard top, which when fitted gave the SL saloon car like civility. Many owners never removed them, which is a shame as the car looks just as good with the soft top deployed.
Towards the end of the R107’s production run in 1985, some new engines were introduced. The 215bhp 4.2-litre V8 replaced the ageing 3.8 and came equipped with the now standard 4-speed automatic gearbox, this combination may well be the sweet spot in the range, with power aplenty yet with reasonable economy too.
Figures recorded at the time suggest a 0 to 62mph sprint time of just nine seconds and a top speed of over 130mph. Respectable figures even today. All this power, yet the frugal could be expected to average around 24mpg in ideal conditions, whatever they may be.
In total, R107 generation production numbered around 237,000, but only 2,148 of these 420SLs rolled out of the Sindelfingen factory, making this car a relatively rare beast.
