Why the Mercedes-Benz SL is the perfect four-wheeled investment

Looking for a classic-to-be? This striking two-seat roadster from Mercedes is a safe, sporty bet

Here’s a fun fact: there were 213,089 Mercedes SL-Class R129 produced. Here’s a funner fact: you can still buy one for under £10,000. And, with such a design pedigree, reliable engineering and enviable looks – it is a car destined to only rocket in price. So get in gear early, and invest now.

Why the Mercedes-Benz SL is the perfect four-wheeled investment

What makes the 1989 Mercedes-Benz SL so worthy of investment?

When the R129 was first introduced in 1989, it immediately pulled Mercedes-Benz’s styling into a new era. And, even though it rolled off the production line with just one year of the Eighties to go, it has come to typify this period, of angles and slick but brash styling. As such, the R129 remains one of the most striking cars Mercedes has ever built – and this iconic status deserves it a place in your investment portfolio.

Bruno Sacco, who served as the head of styling at Daimler-Benz for the last quarter of the 20th Century – and the man behind the reinvention of the SL Class – is widely regarded as one of the greatest automotive designers in history, so the car has a weight and respect behind it only afforded to a handful of roadsters. But that wasn’t the only perk to the sports car…

What makes the 1989 Mercedes-Benz SL so special under the bonnet?

The six-cylinder 300 has either 190 bhp or 231 bhp in its 24-valve twin-cam form, whilst the 500 packed a 32-valve 326 bhp V8 under the bonnet. As such, not one R129 was low on performance stats, and when the later five-speed auto was introduced, this upped the technology factor even more. And that’s what makes this the first SL the first great all-round investment. Previous models were beautiful, of that there is no doubt, but this was the first SL that had the muscle to back up its ‘sports car’ label.

And it wasn’t just the engine that impressed – this was the first SL to make use of every electrical gizmo and gadget you could pack into a roadster. The roof was power-operated, the earlier models featured dual-range four-speed automatic gearboxes and some select SLs even had suspension that automatically lowered itself at speed. Even safety was upped electronically – a pop-up roll bar installed, airbags upped and traction and stability systems introduced.

Are there any faults with the 1989 Mercedes-Benz SL you should look out for?

When investing, there are several slight faults or downsides with the R129 that could be exacerbated if you buy a bad example. The separate hard-top, for instance, was a source of consternation for several buyers, so make sure yours affixes and detaches well before buying, and is in good shape. Similarly, there were some slight handling issues with a number of the R129s, so take your potential investment for a spin before committing.
