The passage of time can be unkind, often diminishing cars from their initial glory. However, the Mercedes-Benz SL launched in 1971 defied this trend. The R107 SL generation, in fact, matured and improved throughout its impressive 18-year production run, becoming an icon in its own right.
R107 Mercedes SL: A Car That Matured with Time
The longevity and success of the R107 Mercedes Sl can be attributed to its exceptional engineering from the outset. Mercedes-Benz was renowned for its meticulous build quality during this era, and the R107 had the added pressure of succeeding the beloved W113 ‘Pagoda’ SL. The new model needed to surpass its predecessor in every aspect to satisfy Mercedes’ discerning and affluent clientele. This ambitious goal led to the R107 earning the nickname ‘Panzerwagen’ during its development phase, a testament to its robust and solid construction.
This ‘Panzerwagen’ moniker highlights Mercedes’ design philosophy for the R107. They weren’t aiming to directly compete with the outright sportiness of the Jaguar E-type or the Maserati Ghibli. Instead, the R107 Mercedes SL was conceived as a refined cruiser, a comfortable and stylish grand tourer capable of effortlessly traversing long distances. This focus on cruising comfort also translated into exceptional safety. The SL boasted substantial crash structures, and Mercedes incorporated a padded four-spoke steering wheel to further enhance occupant protection.
To power this more substantial and luxurious roadster, Mercedes turned to its range of V8 engines from their larger saloon models. Initially, the SL was offered as the 350 SL and 350 4.5 SL, with the latter being renamed the 450 SL in 1973. Responding to the fuel crisis of the early 1970s, Mercedes introduced the 280 SL in 1974, featuring a straight-six engine. Six-cylinder engines remained a constant in the SL lineup from this point forward. The 280 SL was eventually replaced by the 300 SL in 1985, which continued until the end of the R107’s production. Further V8 engine options were added over the years, including the 380 SL, 420 SL, 500 SL, and culminating in the powerful 560 SL as the ultimate iteration of the Mercedes roadster.
Throughout its extensive lifespan, the R107 Mercedes SL benefited from continuous improvements. ABS anti-lock brakes became available from March 1980, and a driver’s airbag was offered as an option from early 1982. Also in 1980, the previously optional hardtop became standard equipment on all SL models, enhancing its year-round usability and appeal. Even in its later years, Mercedes continued to innovate, equipping all versions with a closed-loop catalytic converter in mid-1985.
The inherent strength and build quality of the R107 Mercedes SL have resulted in a high survival rate. Of the 237,287 examples produced between 1971 and 1989, a significant number remain in circulation today. This abundance makes the R107 SL an appealing blend of classic roadster charm and everyday usability. Crucially, their relative availability compared to the more exclusive Pagoda SL means that prices remain accessible to a wider range of enthusiasts.
Driving the Mercedes-Benz R107 SL: Comfort and Capability
The R107 Mercedes-Benz SL was designed with the American concept of a ‘personal luxury car’ firmly in mind, and this is reflected in its driving character. While early models were equipped with large-capacity V8 engines, their performance and sound were notably more refined compared to the more boisterous American muscle cars that were popular when the SL was introduced. Mercedes positioned the SL as a comfortable and luxurious vehicle capable of brisk performance when required. It wasn’t as agile as an Aston Martin DBS, nor as rapid as a Ferrari Daytona, but the SL offered far greater practicality for daily use and all-weather driving.
Remarkably, these qualities have endured. Even early R107 models, now over 50 years old, remain remarkably usable and easy to drive in modern conditions. The majority of original buyers opted for the four-speed automatic gearbox, even when a manual was available. Consequently, cars equipped with the four or five-speed manual transmissions are now exceptionally rare finds.
Performance is best described as brisk rather than outright fast. The initial 350 SL could achieve 0-60 mph in around nine seconds, while the later 500 SL reduced this to approximately seven seconds. The 300 SL, with a 0-60 mph time of 8.4 seconds, strikes a compelling balance. Many consider the 300 SL’s straight-six engine to be the sweet spot in the range, offering a pleasing driving experience without the fuel consumption of the V8s, if you are willing to forgo the distinctive V8 rumble.
Regardless of the engine and transmission choice, the R107 SL encourages a relaxed driving style, well within its performance limits. When pushed harder, the handling is predictable and safe, with the front end exhibiting understeer well before the rear wheels lose traction. Therefore, attempting to emulate racing drivers of the past is not where the R107 shines. Instead, it’s far more rewarding to ease back, appreciate the ample mid-range torque from the refined engines, and enjoy the solid feel of the car. The R107’s robust construction eliminates almost any scuttle shake or body flex, even on rough road surfaces.
There’s a noticeable evolution in the R107 SL’s driving dynamics as the model progressed through its production run. Earlier models tend to have softer suspension and less direct steering feel. Later versions offer a more responsive and precise driving experience, although they still prioritize comfort over outright sportiness compared to contemporary BMWs. With the soft top lowered, the SL is in its element. The generously sized seats provide excellent support, and wind buffeting in the cabin is minimal even at higher speeds. Raising the soft top provides effective weather protection, although it’s not particularly quiet. For a more hushed experience, fitting the hardtop significantly reduces road and wind noise.
Owning an R107 Mercedes SL: Costs and Value
The R107 generation of Mercedes SL exhibits a wider price range than many comparable upmarket roadsters from the same era. Condition plays a significant role in determining value. A poorly maintained example requiring extensive restoration will ultimately cost considerably more than purchasing an SL already in good condition. This disparity keeps the value of neglected cars relatively low, making seemingly inexpensive examples potentially risky buys.
At the entry point of the R107 SL market, a running and driving SL 280 can be found for around £10,000. While these cars will require cosmetic and mechanical attention to bring them up to standard, they represent an accessible entry point to R107 SL ownership. The 300 SL is generally more desirable and commands a premium of approximately £3,000 for a car in ‘fair’ condition. Early 350 and 450 V8 models tend to be priced similarly to the 300 SL, irrespective of condition. Consequently, expect to pay around £25,000 for a well-sorted 300, 350, or 450 SL, with top-condition examples reaching up to £45,000. A pristine 280 SL can fetch prices in the high £30,000s.
The 500 SL, featuring the largest engine offered to UK buyers, typically sells for just over £24,000 in ‘good’ condition. However, pristine, low-mileage examples can command double this amount. The 560 SL was not officially sold in the UK, so any examples present will be imports, primarily from the US or Europe. This factor generally keeps 560 SL prices in line with the 500 SL. It’s essential to ensure that any imported 560 SL has had its headlights converted for driving on the left-hand side of the road in the UK.
R107 Mercedes SL Buying Guide: What to Look For
This generation of SL is known for its durability and ability to withstand regular use, but neglect will inevitably take its toll. Bodywork is the primary area of concern and potentially the most expensive aspect of restoring an R107. A thorough pre-purchase inspection of the body is crucial, as rust can often be concealed beneath fresh paint.
Begin your inspection at the front wings, above the headlights, checking for any signs of bubbling paint or previous poor repairs. Carefully examine the bonnet, boot lid, doors, wheel arches, sills, and floors for corrosion. Pay particular attention to the windscreen surround and the bulkhead area, where water can accumulate and cause rust. The bumpers are prone to rusting from behind, so reach behind them to check for roughness. If the car comes with its hardtop, inspect it thoroughly for any damage or corrosion as well.
Inside the cabin, the trim is generally hard-wearing, but check the seat fabric for wear, as matching original cloth can be difficult. Leather upholstery is easier to restore. Complete soft tops or replacement rear plastic screens are available if needed. Mercedes’ MB-Tex plastic upholstery is exceptionally resilient, and significant wear may indicate a very hard life.
Verify that all electrical systems within the cabin are functioning correctly, including the central locking, which operates on a vacuum system and can be prone to leaks. Dampness inside the cabin typically indicates worn hood and window seals or corrosion in the bulkhead.
The engines, both six-cylinder and V8, are generally robust and reliable. However, V8 engines can sometimes suffer from noisy tappets. This issue may be resolved with a simple oil change, but more severe wear might require rocker arm replacement. The radiator is another common weak point, being vulnerable to stone damage due to its exposed front location. Check for any signs of overheating during a test drive or coolant leaks from the radiator.
The R107 SL should provide a smooth and quiet driving experience. Any squeaks or rattles often point to worn suspension bushes, which are relatively straightforward for a specialist to replace and will improve both handling and ride comfort. Vague steering feel is usually attributable to a worn steering box. While adjustment can temporarily alleviate slack, eventual rebuild or replacement may be necessary. New steering boxes are still available from Mercedes, but they are a significant expense. The steering system also incorporates a damper, which wears with age and is advisable to replace concurrently with steering box work.
Which R107 Mercedes SL is Right for You?
Given the R107 Mercedes SL’s long production run and the diverse range of engines offered, there’s likely an ideal model to suit most preferences. Six-cylinder versions are generally more affordable to purchase and run than the larger V8 models. However, a 350 or 380 SL may offer comparable fuel economy to a 280 or 300 SL. The straight-six cars do offer slightly more agile handling due to reduced front-end weight, and their engines are generally more eager to rev.
While the SL isn’t a sports car in the mold of a Porsche 911, the 1985-onwards 300 SL is arguably the best all-around choice for entering R107 ownership. It provides cruising capability comparable to many V8 models, combined with excellent refinement and reasonable fuel economy for more frequent use.
The 300 SL also benefited from Mercedes’ chassis improvements, including revised suspension geometry for enhanced handling and steering feel, lower profile tires as standard, and a front chin spoiler to reduce front-end lift at higher speeds.
For those who desire a V8-powered Mercedes-Benz SL, the 500 SL is the prime target in the UK market. While 560 SL models offer even greater performance, they are imports and potentially more complex to maintain in the UK. However, a well-maintained 560 SL should not be dismissed. The 500 SL provides a rewarding blend of performance with only marginally worse fuel consumption compared to smaller-engined variants.
Later 500 SL versions from mid-1985 onwards gained increased power, making condition a more critical factor than age when choosing between these models. Ultimately, the R107 Mercedes SL remains a compelling classic, offering a blend of luxury, comfort, and timeless style that continues to captivate enthusiasts worldwide.
