After nearly four decades of being on the road this beautiful SL is just as good today as it was during the 80s.

Mercedes-Benz have produced the 'Sport Leicht' aka 'SL' since 1954. The R107 generation first introduced in 1971, and world-renowned for its performance, styling, and reliability. The 4.2L V8 engine is mated to a four-speed auto, enclosed in a two-door monocoque shell with independent suspension, coil springs and anti-roll bars at the front and rear. The steering was power-assisted featuring the Daimler-Benz re-circulating ball system. Over its 17 years of production, the R107 was made available to a very wide audience with eight different engine variants.

Between 1985-1989 the more powerful ~215BHP 90° V8 engine powered the 420SL, this particular model with the 4.2L engine is one of the rarest R107s, just ~2,148 produced. The engine enjoyed the introduction of Bosch’s KE-Jetronic fuel injection system, varying from the earlier, all mechanical system by the introduction of a more modern engine management "computer", which controlled idle speed, fuel rate, and air/fuel mixture, making the 420 SL able to put out a decent MPG with en economical driving style.

This example comes to market from 4 years ownership, and has previously been cosmetically restored by 4-star classics. It presents in very good condition as a UK RHD, 6 former keepers recorded, and comes with the hard-top. In current ownership, the suspension has been renewed and upgraded, and the car comes to market with a recent MOT. In "Arctic White" over a navy leather interior, it's a striking example of the marques flagship roadster.

This auction listing was written from information supplied by Alan after meeting Jag the owner, and having visited and photographed the vehicle.

Meet the owner

Thousands have been spent on the preservation of this V8 R107, I love the classic looks and colour combo on this one.

Jag has owned this SL for ~4 years, he's always admired the R107 shape from an early age, as tells us another reason for this purchase was the rarity (~2,148 produced) and sweet spot the 420 SL finds itself in. Finished in Arctic White (147) over navy interior, this example really stood out to him.

In his ownership, Jag has had the springs and shocks renewed with Eibach springs and Bilstein gas shock absorbers, he's also spent time fixing a few interior items like the fuel gauge and wing mirrors. Jag admits he's not using the car enough to justify ownership and due to using his other classics more often has decided to bring this lovely example to auction with us. He'll be more than happy to answer any questions you may have in the comments below.

Gleaming with Hollywood elegance, the classic SL shape is timeless and a firm favourite amongst enthusiasts.

Wheels and Tyres

This being a 1987 car, it is fitted with the 15" facelift alloys, these present in good condition all around. We noticed a very minor mark on the offside rear alloy.

The car is fitted with Dunlop SP Sport 200 all round. The tyres appear in used condition, dated 2001 with slight cracking to the side walls, nothing too serious with the car passing a recent MOT. View the images to see the details.


The bodywork of this 420 SL looks in great condition, with all the panel gaps around the car look to align well. This being a later facelift model, the cars featured galvanised bodywork, helping to preserve the cars over time. During our visit we didn't spot any obvious dinks down the flanks of the car, everything looking crisp and sharp. Both the doors, boot, and bonnet open and close with ease, and door shuts/sills which are typically problem areas all looked clean and visually free of issue.

We've highlighted in more detail our observations through our hi-resolution images and videos, so please take time to look through all the media files for a detailed view at what’s on offer, and for you to assess the condition of the car for yourselves.


Finished in a "Arctic White", the car was resprayed, along with new front wings being fitted and a full service at the cost of ~£4,500 in 2010 by 4-Star classics, the paint appeared in great condition on our visit, good lustre to the paint, it's a striking choice.

The images are taken from a few different angles to show off the car as you would see it if you were standing there for yourselves. So please take the time to fully assess these hi-resolution images and videos of the car, for you to make up your own minds about the condition of the paint.

Glass and Trim

The glass on this example looks good and in line with the mileage and ownership, we didn't notice any major chips, cracks, or discolouration on our visit. The window seals look good too and in line with the rest of the condition of the car. Along the chrome trim we did notice small signs of pitting in areas, view the image gallery to see the detail.

The convertible hood has very small wear to the nearside plastic window from folding as pictured.


Furnished with high-quality coloured leather, still clean, elegant and comforting ~35 years later.

Seats and Carpets

Comfortable SL navy leather seats are fitted in the front of this roadster. We did notice some very light wear to driver's bolster as you would expect with age, but this is quite minor and the interior has stood the test of time well.


Fitted with the classic Mercedes-Benz black dashboard, this had no signs of any major damage or scuffs and appeared highly original. The top of the dash is trimmed with matching blue plastic, with this car having likely been garaged its whole life does not suffer and warping or cracks in the top of the dash.

No warning lights were displayed when we started the car and the odometer showed a reading of 93,012 on our visit. In the current ownership, Jag has completed some work to get the fuel gauge working, and the timing clock too, some small items that weren't working when he purchased ~4 years ago.

Steering Wheel / Gear Stick

The original Mercedes steering wheel and gear selector are presented in great condition and show very few signs of use.

Take a look at the photos and videos for a closer view of the cabin.


The dashing good looks with the desirable V8 under the hood, the perfect blend of power and style.

Engine and Gearbox

Please watch the "On the Road" video to see the car being started from cold, then run when up to temperature. On our short trip out, the car went through the gears with ease.

Jag mentioned to us that with this being the 420 SL, it's actually surprising the MPG that can be achieved when drive carefully, yet you can still get that classic V8 experience with a more forceful push of the accelerator.

Suspension and Brakes

The cars suspension has been renewed and fitted with Eibach springs and Bilstein gas shock absorbers in the current ownership as pictured. The suspension has been lowered slightly so the wheels fill the arches that little bit more the higher standard set-up.

Jag reports regular maintenance on this example has been carried out throughout his ownership.

The Drive

The Mercedes V8 offers plently of poke for a convertible, with attractive styling, you'll have the attention of everyone.

Watch the mechanical video to see the car start from cold and get the V8 up to temperature along some local roads.

Electrics and Other

Most of the electrical fittings are said to be fully functional. Jag is unsure if the 10-change CD player is functional. As mentioned Jag has repaired some interior items including; fuel gauge, interior clock and passenger side electric remote mirror.

We did notice a small patch of surface corrosion in the boot near the spare tyre. Please take a look at the images and videos for a detailed tour of this car's exterior and interior.

History and Paperwork

A desirable V8 R107 SL finished in period correct Acrtic White over navy leather interior, this UK car has a great amount of genuine main dealer history dating back to production.

This car is coming out of 4 years of ownership with Jag. Take a look at the media to see all the history included in the sale of the car, including the extensive work carried out from 2010 by 4-Star classics. If you're in the market for a previously restored V8 SL, with a great deal of main dealer history, then this is the example for you.

Jag will be more than happy to answer any questions you have about the car in the comments below.
