* BHP stands for “Brake Horsepower” and is a measure of an engine’s power. It is a standard unit used to measure the engine’s strength before any losses from accessories like the alternator, water pump, or other drivetrain components are deducted.

Overview of SL R107 features by generation
How to identify a USA version of the R107?
There are only three engine variants that were factory-supplied to the USA: the 450 SL, 380 SL, and 560 SL. If you come across a different engine type with a USA registration or the large USA bumpers, it is not original. At that time, there was a ‘grey market’ where, for example, a 280 SL or 500 SL was exported to the USA after its delivery in Europe. This mainly occurred because those models were not officially available for sale there. In some states, owners could retain the original bumpers, while in others, mandatory modifications were made to comply with local regulations. As a result, you might sometimes see a 280 SL with the large USA bumpers.
Identifying features
- Taillights with a red end section
- Stoplight on the trunk lid
- Battery in the trunk on all USA models from 1974
- Speedometer in mph instead of km/h
- Headlights with dual round lamps
- Large bumpers front and rear
In our workshop, we regularly perform the visual conversion of a USA version to the ‘European’ version. This usually includes the headlights, bumpers, taillights, third brake light on the trunk, and the speedometer. This transforms the vehicles into the more sought-after and elegant version of the R107. A high-quality conversion is a significant investment but adds substantial value. A USA version is worth more after the conversion.
Permanent identifying features after a conversion are the battery in the trunk, the engine number, and the original attachment of the front bumper to the chassis.
The significant variation in quality. The main factor in determining the value of a Mercedes-Benz R107 is the condition of the vehicle. If you want a car that is both aesthetically and technically in good shape, it is always a better financial choice in the long run to opt for one in the best condition. The costs of quality restoration for these cars can quickly add up. In our workshop, we often see projects requiring repairs that exceed the purchase price. Often, the owner has made a common mistake by choosing a poorly maintained example due to its lower purchase price.
Differences between generations and models. Throughout the long production period, there were three generations of the R107 produced, each with different engine options. Within each generation, there are USA models that are generally worth less, partly due to their larger bumpers and lower power. A USA 380 SL with 155 hp is usually worth less than a European version of the 380 SL with 218 hp. Additionally, there is a significant difference in production numbers between the various models. A model with fewer units produced generally appreciates in value.
Which Mercedes-Benz SL R107 you should buy depends on your goals with the car. Are you looking for a lot of engine power? Comfortable and long drives? Or stylish cruising with a true classic feel? Additionally, your budget and long-term goals play a significant role. All models have their pros and cons, and any R107 can be a solid vehicle. The most important factor remains the overall condition of the car. You will get much more enjoyment from a less popular USA version of the 380 SL in excellent condition than from a sought-after third-generation 500 SL in poor condition.
Make sure you know what you’re doing. As with all major purchases and investments, when buying a classic Mercedes-Benz, it’s best to make a well-informed decision. Seek guidance or ensure that you are knowledgeable both technically and regarding the model. Looking for someone to assist with your purchase?

Consider a budget for repairs after purchase. From practical experience, we know that almost every Mercedes R107 for sale will need overdue maintenance and repairs. If you allocate the entire budget to the purchase price, you are guaranteed to face unexpected costs later on. The solution? Allocate a budget for repairs when making the purchase.
Buy the right R107 for your goals. Do you want a perfect car with minimal or no issues? Then don’t settle for a vehicle that is worn out and unattractive. Restoration will almost certainly end up costing more than buying a well-maintained car that only needs minor repairs. If the appearance is less important to you but you want to enjoy worry-free long drives, allocate more budget for technical repairs, possibly with less focus on aesthetics.
As a Mercedes R107 specialist, we have clients who drive their cars almost daily or weekly. We also have clients who travel with their R107 three times a year but don’t drive much otherwise. Additionally, there are people who only drive in nice weather and want to keep their car in perfect condition. Every driver has different goals and habits, what matters most is considering your own goals when purchasing your Mercedes.
All-round and versatile
The biggest advantage of the Mercedes-Benz R107 is its versatility. It’s a car that’s enjoyable to drive sporty in the mountains, but also pleasant and comfortable for cruising. Since they still feel modern, there’s no barrier to using this car for a quick trip to the bakery on Sunday. Additionally, you can drive comfortably and without issues to the south of France.Value-retaining with significant potential
The prices of the R107 increase every year. There are no risky spikes that double in value within a year only to drop again, but rather a stable and reliable growth. Over the last five years, we have seen an increase of around €2,500 per year. These cars are currently still undervalued. Expectations are that the value of these models will rise significantly.Reliable and high build quality
Technically sound R107 models can take a beating. A Mercedes-Benz from this era is generally very solid and built to withstand a lot. Cars that are technically sound can be used without problems for a long trip to the south.Safe and suitable for today’s traffic
German safety engineering was a key feature in the 1970s and 1980s. Since the R107 SL belongs to a luxury segment, it represents some of the best Mercedes-Benz had to offer at the time. They come standard with technology that is still relevant and the norm. A Mercedes 107 features four disc brakes as standard, providing very good braking power. Models from 1980 onward offer optional ABS, which became standard on all models from 1986. From 1982, a driver’s airbag was also available as an option. Many cars also feature electric windows, central locking, air conditioning, heated mirrors, and more. Each R107 also has built-in crumple zones and safety standards that were ahead of their time, making you safer in an accident compared to many modern smaller cars.
