A custom-built coupe inspired by the legendary Mercedes-Benz 300 SL has appeared for sale with a staggering $299,950 asking price. While it captures some of the iconic gullwing’s unmistakable styling, there’s one detail that makes it especially unusual: underneath the bodywork is a 2004 Chrysler Crossfire.
Built by Signature Autosports, this particular one-off creation is described as a modern interpretation of the classic 300 SL rather than an exact replica.
The project combines retro-inspired styling with the Crossfire’s Mercedes-derived platform, resulting in a car that blends elements of both old and new.
The asking price places it firmly in exotic car territory. At nearly $300,000, it costs substantially more than a brand-new Mercedes-AMG GT 63 S E Performance, despite retaining the Crossfire’s original V6 powertrain. Whether it’s a work of art or an expensive curiosity will likely depend on the eye of the beholder.
Inspired by an Automotive Icon
From a distance, the replica immediately evokes the original Mercedes-Benz 300 SL thanks to its signature gullwing doors, rounded roofline, and classic coupe proportions.
A closer look reveals that this isn’t intended to be a faithful recreation. The front end features modern LED headlights, reshaped fenders, and a contemporary front splitter rather than the chrome bumper found on the original 300 SL.
Around back, the styling remains closer to the classic design, although the center-mounted dual exhaust and aftermarket Cosmis Racing wheels give the car a distinctly modern appearance. Finished in Bentley Sequin Blue Metallic, the build certainly stands out.
A Crossfire at Its Core
Despite the dramatic transformation, the mechanical package remains largely unchanged from the donor vehicle. The replica is based on a 2004 Chrysler Crossfire, itself heavily derived from the first-generation Mercedes-Benz SLK following the DaimlerChrysler partnership.
Under the hood sits the familiar 3.2-liter naturally aspirated V6 producing approximately 215 horsepower and 229 lb-ft of torque.
Power is sent to the rear wheels through a five-speed automatic transmission, meaning performance is a long way from the original 300 SL’s legendary status—or even many modern sports cars.
The Interior Mixes Old and New
Inside, Signature Autosports has attempted to blend vintage styling with modern components. The cabin features Golden Brown Merino leather upholstery, retro-inspired instrumentation, a painted dashboard, and a classic-looking two-spoke steering wheel.
However, several original Chrysler Crossfire switches and controls remain visible, making the car’s origins difficult to disguise completely. The combination creates an interior that feels unique, even if it doesn’t fully hide its early-2000s roots.
A Price That Raises Eyebrows
The biggest talking point may not be the styling, but the price. At $299,950, this custom build costs nearly ten times what a new Chrysler Crossfire sold for when it debuted in the mid-2000s. It also undercuts the appeal of several genuine high-end performance cars available today, including new Mercedes-AMG models offering vastly superior performance and factory engineering.
Of course, buyers considering a hand-built one-off like this aren’t necessarily shopping based on horsepower or lap times. Exclusivity and craftsmanship often carry their own premium.
Even so, asking nearly $300,000 for a heavily modified Chrysler Crossfire is certain to divide enthusiasts. Some will appreciate the creativity and custom fabrication, while others may struggle to overlook the donor car hiding beneath the gullwing doors.
