Many auto enthusiasts consider the Mercedes-Benz 300SL as the most collectible car on the market. The car maker is an obvious household name in the car market, knowing for sophisticated German engineering and safety innovations,. but it pretty much all starts with these Gullwings and Roadsters.

Whether you’re cashing in on a long-term investment or making space in your garage for other collectibles, you may be looking to sell 300SL. This comprehensive guide will walk you through the process of how to list a 300SL for sale.

Mercedes-Benz 300SL History

It’s not surprising that the classic 300SL is still a premiere, sought-after roadster. But where did it all begin? The Gullwing 300SL roadster was an adaptation of the W194 race chassis, developed by Daimler-Benz in 1952. It was the first sports-car designed by the iconic Mercedes-Benz manufacturer. 

Targeted at wealthy Americans, Daimler unveiled the classic 300SL at the New York Motor Show in 1954. Car enthusiasts touted the 300SL as the fastest production car in the world. 

Compared to cars produced at that time, the 300 SL was light years ahead. So it’s no wonder it is still turning heads till today. Its iconic doors have remained a standout feature to date and are why the nickname “Gullwing Mercedes” still carries clout to this day.

At the time of launch, the 300 SL original price was a remarkable $11,000. You could purchase a Corvette and four Jaguar sedans with what it would cost you to buy a new Mercedes 300 SL!

The Model Years

1954 – 1963

Daimler produced the 300SL Gullwing Coupe and 300SL Roadsters at Sindelfingen, Germany, from 1954 to 1963. Both models were ahead of their time and shared the same parts and engineering philosophies, and craftsmanship throughout their run on the production line. 

1954–1957 (Gullwing Coupe)

Inspired by the racing cars of 1952 and beyond, Mercedes-Benz built 1,400 Gullwing Coupes between 1954 and 1957. Nowadays, the Gullwing value can be anywhere from around $1 million to up to and beyond $3 million. 

These beauties were usually silver, gray, or metallic, with the 300SL Gullwing interior furnished in plaid fabric and vinyl. You could get a radio and unique luggage space custom-fitted by the Daimler powerhouse on order. Its instrument panel also had the same color as the car’s exterior. The 300SL Gullwing engine was a standard 3.0L.

This model also had rudge wheel parts & accessories. These additions were available at the factory’s request if you didn’t like the conventional bolt-on wheels. 

1957–1963 (Roadster)

The 300SL Roadster bore a substantial outward similarity to the Coupe, but that was where it ended. 

One could argue that it was much more than a Gullwing 300 SL with a soft top. It had more space and conventional doors with roll-down windows. Also, the instrumentation received an upgrade with better heating controls. 

Admittedly, it had lesser fuel capacity, but that was a necessary sacrifice. Alterations to the fuel capacity made room for a spare tire. 

Daimler-Benz produced 1,858 Roadster 300SL models from 1957 to 1963. Nowadays, the 300SL Roadster value is anywhere between $500,000 to over 1 million.

300SL Driving/Performance

The 300SL is still a fantastic drive. It’s quiet at most speeds and purrs along till you get the engine revving past 4000 rpm. Once you get the engine to that point, it becomes a loud machine-gun. When you drive the 300 SL, you need planning, timing, and forethought to get the best out of its legendary engine, and that’s what makes it so much fun to drive! 

The 300 SL has a four-speed manual transmission, with an incredible acceleration time due to its low gravity. When driving the Gullwing 300SL, the feeling of rocket-like acceleration is one you won’t forget in a hurry. It can go from 0 — 60mph within just a few seconds! 

The 300 SL’s driving experience bests even those Jaguar sports cars of it’s time. It’s also an ergonomically sound vehicle — with a build quality that most modern cars would envy.

Current Condition

When assessing the condition, you would need to answer the following questions:

  • In what condition is the engine?
  • Is the interior clean and intact?
  • Would a new owner need to do any significant work on its outward appearance?
  • Are you willing to service or fix any engine issues before selling?


Silver and white are the most popular colors of the Gullwing 300SL. If your car sports any of these colors, it’s sure to command a premium.

However, don’t despair if your version has one of the more adventurous colors. It’s still a Gullwing 300SL, after all.


Mileage isn’t usually a significant issue, especially if your old Mercedes 300SL is in prime condition. But you also want to sell a car that hasn’t received a flogging until it is on its dying legs. 

Various free classic car sites enable you to do preliminary research on an estimated price for your Mercedes 300SL, depending on the vehicle condition and model. Here are three reputable sources: 

  1. CARGUIDE.COM: CARGUIDE.COM is an online resource with a proprietary tool for estimating the value of a classic car. 
  2. National Automobile Dealers Association (NADA): NADA has a series of online searchable guides that can quickly give you a range of prices for your classic car depending on factors such as year, model, or trim. 
  3. The Collector Car Market Review (CCMR): The CCMR compiles a report that tracks sale prices and other data sources and then uses the data to estimate a classic car’s value. 

Remember that you will still need to get an official appraisal from a qualified appraiser when you sell it, and even then there’s always the time it could take to move a car like this on the private buyer marketplace.

Restored vs. Project and Barn Find Cars

A restored car will usually sell for more than a barn-find car. The buyer of a barn-find 300 SL Mercedes would still need to spend a considerable amount of money bringing the car back to shape, depending on the damage. With a restored car, the buyer is sure he has no work to do. 

Does the Engine Number and VIN Match the Paperwork?

If you are trying to sell a 300SL in which the engine number and VIN don’t match the title, you need to clear that up before you get a serious buyer. Mismatches like this could be due to various clerical errors or could mean that you bought a stolen car.

Have You Serviced It Professionally and Driven It Regularly?

Without regular driving or maintenance, any car is likely to degrade, even the Gullwing 300SL roadster. It would be best to be transparent with the buyer about its maintenance history and how often your 300 SL hits the road. This information gives a sense of the overall condition of the car.

The Mercedes-Benz could cost you as little as $100 to $1,000 to maintain annually, and $500 on the average. The cost depends on state of the car obviously, and the mechanic you use, but these are relatively simple machines (compared to today) and parts are available.

How Often Should I Get My 300 SL Serviced?

Ideally, you should get your 300SL serviced once a year.
