About the Mercedes-Benz S-Class W108 / W109

The Mercedes-Benz W108 and W109, manufactured globally between 1965 and 1973, represent the final generation of the elegant, understated Paul Bracq-designed S-Class predecessors, with a total of 383,072 units produced. While the W108 utilised conventional steel-spring suspension and standard wheelbase lengths, the W109 was a technical powerhouse exclusively fitted with self-levelling air suspension and a lengthened chassis, culminating in the monstrous 300SEL 6.3 which successfully shoehorned a limousine V8 into an executive sedan body. In the 2026 Australian market, the W108/W109 series has attained a high level of desirability, particularly for original, Australian-delivered 280SE 3.5 and 300SEL 6.3 models, which are increasingly viewed as "blue-chip" classic investments. The buyer pool in Australia is remarkably robust, consisting of heritage-focused collectors who prize the model's peerless build quality and performance enthusiasts who target the 6.3 as the spiritual ancestor of the modern AMG saloon. Locally, market value remains exceptionally firm for well-preserved survivors, as 2026 buyers are prioritising vehicles with a documented service history from specialists like Bernie Smith Classic Cars in Melbourne or Oldtimer Australia to ensure the intricate pneumatic systems and mechanical fuel injection are in peak order. The Australian community also boasts a sophisticated restoration scene, where many owners opt for "sympathetic" upgrades to modern electronic ignition and cooling systems to better suit our harsh local driving conditions. For the Australian aficionado, the W108/W109 is a masterclass in timeless design and engineering integrity, continuing to be a celebrated fixture at premier events like Motorclassica and within the Mercedes-Benz Club of Australia.
