Mercedes-Benz has been a formidable force when it comes to producing sports cars for decades. Not only have its models dominated a wide variety of motorsport disciplines – with success coming in the form of early Silver Arrows racers, DTM legends, and more recently, on F1 tracks with Lewis Hamilton at the helm – its road-going efforts have also been historically brilliant.
The 300 SL with its wild gullwing doors kicked it off, and every iteration of the mighty SL since has played an important role for the brand. Even now, while two-door sports cars are declining in popularity, Mercedes continues to offer the luxurious SL with a number of potent powertrains and luxury interiors, and for deep-pocketed individuals, these still stand out as some of the best cars money can buy in 2025. However, what about those of us with somewhat shallower pockets, do we have to miss out on all the fun?
Fortunately, no. In fact, those who are daring enough can bag themselves a V12-powered gem of an SL that has been overlooked for far too long, and getting hold of one is much more affordable than you might first think.
A Brief History Of Mercedes-Benz Sports Cars

Sure, the mighty 300 SL kick-started the movement, but that was always a racer first and a road car second. Arguably, the 190 SL which followed is a more honest starting point for the SL’s road-going lineage, and looking back at it, it’s clear to see how little its original recipe has been changed. Sure, modern SL models house boosted V8 engines and every gadget you can think of, but at their core, they are still two-seat, two-door drop-tops with an engine up-front, drive at the rear, and an exquisite cabin in the middle.
Little was done to ruin this recipe at all through the SL’s various generations, which is likely why each generation was able to stay in production for so long. Instead of pushing the boat out with radical designs and daring drivetrains, Mercedes simply developed well-engineered and enjoyable sports cars for its SL range.
The Introduction Of A V12-Powered SL

However, the engineers at Mercedes did eventually get a little tired of playing it safe after 35 years or so, and decided to step up their game a little. The resulting creation arrived in the mid 1990s, in the form of a 6.0-liter V12-powered R129 SL. It was dubbed the SL 600, it was produced in smaller numbers (likely due to the V12-sized asking price), and today it’s a collector’s dream, overshadowed only by AMG-badged variants.
Clearly, this tweak to the recipe went down remarkably well. So well, in fact, that Mercedes opted to keep a V12 in place for the R230 generation which followed in the ’00s. It’s this later SL 600 that represents such a bargain buy in 2025, but before unearthing what one will cost today, it’s first important to see what perks a 12-cylinder Mercedes sports car actually comes with.
The R230 SL 600: Performance And Prestige Perfectly Balanced

Whereas the previous-gen SL 600 sported a naturally aspirated 6.0-liter V12, this R230-gen had to step things up a bit. In order to do so, Mercedes chose to fit a slightly smaller V12, with a capacity of 5.5 liters, but then furnished it with a pair of turbochargers.
The outcome was really quite awesome considering this is a non-AMG model, with 493 horses to play with, and a fairly astonishing 590 lb-ft of torque. For a fairly reserved looking convertible, those are frankly awesome numbers, and more at home on a Ferrari or Lamborghini’s spec sheet, rather than here.

In addition to a great-big engine, the flagship SL models also sport a few more features which lesser-powered variants don’t benefit from. For example, the SL 600 enjoys Active Body Control suspension, which is an electronically controlled hydro-pneumatic suspension.
The resulting ride is silky smooth, and just what you’d expect from a range-topping Mercedes of the era. It also helps keep the body sitting nice and even when putting those 493 horses to work, and up front, you’ll find the same brakes that keep the SL 55 AMG in check, albeit behind a more reserved set of wheels.
The Aging SL Is 2026’s Answer To 12 Cylinders On A Budget

While the engine and luxury features of the SL are certainly great talking points, perhaps the most interesting thing about these cars is just how cheaply they can be picked up for in 2026. Despite setting the original owners back almost $130,000 before any options, these V12-powered SLs can now be had from just north of $10,000. That’s less than half what you’ll pay for a Hyundai Venue, which is the cheapest new car on sale in the USA.
Good examples go for around $20,500, which looks to be accurate for lower mileage examples, which undoubtedly have a little less wear and tear, and perhaps more consistent service histories, and fewer owners.
Here’s How The SL 600 Compares To Other Comparable Sports Cars Of The Early 2000s

You’d struggle to find any of the SL 600’s main rivals selling in usable condition for around $10,000, even though they’ve all been hit pretty hard by the depreciation stick themselves. For example, Aston Martin’s DB7 Vantage Volante is considered relatively affordable, although they regularly sell for double what a good SL 600 commands, and the same is true for period 911 Cabriolets as well.
You might be able to sneak into an M3 Convertible or soft-top XK8 for similar money, but neither offer the V12 experience of the Mercedes. Sure, they are perhaps more sporting, especially the M3, but when it comes to crossing continents and wafting down highways, the SL takes some beating, especially for the money.
V12 Mercedes Ownership Isn’t To Be Taken Lightly

It might seem tempting, forking out $10,000 or so for a Mercedes sports car with a V12 under the hood, but there is always a catch. In this instance, the catch is that you’ll need deep pockets to swallow the repair and maintenance costs, which are very much in-line with its original $130K asking price. That takes some of the shine away from this otherwise beautiful bargain. Common issues include rust, faulty roof mechanisms, air suspension issues, and – while the engine itself is largely considered very reliable – if it does have serious issues, you’d be better off breaking it for parts than you would be repairing it.
So, yes, you can snag this 12-cylinder sports car for cheap, but be mindful of what bills might be lurking around the corner if you do. Perhaps the best approach would be to buy a good, low-mileage and well-maintained one, rip about in it for the summer, and then sell it before the bills have a chance to appear. Best of luck.
