CLASSIC FORM. CONTEMPORARY SOUL.
The Art of the
Bespoke Replica
At Signature Autosports, we don’t just recreate legends — we reimagine them with purpose, precision, and personality.
Each Signature SL™ replica is built to order, allowing you to shape every detail to match your vision — from vintage-correct switchgear and authentic upholstery to modern performance upgrades, digital conveniences, and custom paintwork.
Whether you're drawn to the sculpted silhouette of the Gullwing or the open-air allure of the Roadster, your vehicle is more than a nod to history — it’s a rolling expression of individual craftsmanship, tailored refinement, and timeless design.
This isn’t restoration. This is resurrection — done your way.
A TWENTIETH-CENTURY ICON.
REIMAGINED FOR THE TWENTY-FIRST.

300 SL
CLASSIC INTERIOR
For purists who crave the elegance of the original 1950s icon, the Signature 300 SL features handcrafted interiors that mirror the legendary styling of the original 300 SL. From the slim two-spoke steering wheel to period-correct instruments, upholstery and finishes, these builds transport you straight back to the golden age of automotive design — with none of the headaches of mid-century mechanics.
THE 300 SL GULLWING
With its unmistakable upward-swinging doors and aggressive yet elegant stance, the Signature 300 SL Gullwing delivers unmatched curb appeal and classic bravado. It's not just a tribute — it’s a time machine in tailored sheet metal.
THE 300 SL CONVERTIBLE
Refined and rakish, the Signature 300 SL Convertible offers wind-in-your-hair freedom with a sculpted silhouette that’s pure 1950s perfection. Every stitch, switch, and surface honors the golden era of grand touring — minus the overheating and hard starts.
THE 300 SL ROADSTER
No top. No limits. The Signature 300 SL Roadster strips it down to the essentials — pure, uninterrupted bodylines and an open-air cockpit that transforms every drive into an event. This is elegance in its rawest, most intoxicating form.
SIGNATURE AUTOSPORTS
355 SL
™
MODERN INTERIOR
Designed for those who appreciate the icon but live in the now, the Signature 355 SL™ marries vintage exterior styling with a modern Mercedes-Benz® interior and tech suite. Still built on R171 and R172 chassis, these versions carry over the factory amenities, including instrument clusters, infotainment, and climate controls — delivering a luxurious, reliable, and drivable classic you’ll want to take out every weekend.
THE 355 SL™ GULLWING
The iconic silhouette stays — but the experience evolves. The Signature 355 SL™ Gullwing blends legendary form with cutting-edge function, featuring a modern Mercedes-Benz interior, digital interfaces, and real-world reliability. You won’t just collect stares — you’ll collect miles.
THE 355 SL™ CONVERTIBLE
Power top. Climate control. Bluetooth. But still unmistakably a classic. The Signature 355 SL™ Convertible offers all the open-air charm of its vintage counterpart, infused with the comfort and convenience today’s roads demand.
THE 355 SL™ ROADSTER
Topless and tech-savvy, the Signature 355 SL™ Roadster delivers visceral thrills with every press of the throttle. Modern suspension, high-end materials, and a driver-focused cockpit make this the ultimate reimagined classic — built to be driven, not just admired.

THE SIGNATURE DIFFERENCE
Defying Convention.
Defining Excellence.
I’m Aaron, the founder of Signature Autosports — and like the rest of our team, I’m a car guy through and through. We didn’t get into this business because it was trendy. We got into it because it’s been in our blood for decades.
Most of us are over 40, and we’re still doing what we love: building, driving, obsessing over, and talking about cars and trucks. That passion shows in everything we do — from our first conversation with you to the moment your keys hit your hand.
We’re also a licensed North Carolina auto dealer, which means your purchase process is smooth, secure, and professionally handled from start to finish.
No surprises. No headaches.
Just real people, real craftsmanship, and a better way to buy.
WE'RE A FAMILY BUSINESS

No need to put up with pushy salespeople; you'll deal with me directly. You've got my number, and I encourage you to call or text me any time. I'll even provide you with regular status updates so you know exactly where we are during the process.
Let us take the stress out of your hunt for the perfect vehicle and make it a fun and enjoyable experience.
I look forward to meeting you!
