My expert opinion and pricing analysis on the offer
This East Coast Gullwings Mercedes-Benz 300SL Gullwing Replica is currently live on Bring a Trailer, with the auction ending in approximately 2 days and a current bid of over $140,000 and climbing. The car wears hand-laid fiberglass and vinylester resin bodywork finished in black over a shortened 1977 Chevrolet Corvette C3 chassis, and power comes from a rebuilt 5.7-liter Vortec V8 paired with a ZF six-speed manual transmission sourced from a 1992 Corvette ZR1. The digital odometer shows 29 miles, with the seller estimating approximately 300 total miles since the build was completed.
According to Classic.com, the average sale price for a Mercedes-Benz 300SL Gullwing Replica is $214,725. The highest recorded sale was $325,000 for a 1955 replica in February 2026, while the lowest was $55,000 for a project-grade example in January 2022. The range is enormous because the 300SL replica market is less about the concept of “replica” and more about the quality, provenance, and details of each individual build. At the top end, Ostermeier/Gullwing Cars builds have approached and exceeded $400,000 at auction, with one failing to meet its reserve at $430,000 on Bring a Trailer. A Quint Motorcars example sold at Mecum for approximately $240,000 in 2024.
My prediction is a final hammer price in the range of $150,000 to $225,000. The ZF six-speed from a ZR1 is a genuinely interesting powertrain choice that adds usability and cool factor; the build quality appears serious, and the family provenance to Quint Motorcars is a story that collectors will appreciate.
The title situation is the elephant in the room. The car is sold on an expired Connecticut registration tied to the donor Corvette’s VIN, and that will require some paperwork navigation by the buyer, depending on their state. It’s not insurmountable, but it’s not as clean as a proper MSO or replica title. For the right buyer, someone who values the craft, the family story, and the sheer audacity of building a Gullwing replica in your shop because your uncle was Herman Quint, this is a compelling car at whatever the final bid lands.

East Coast Gullwings Mercedes-Benz 300SL Gullwing Replica listing details
The foundation of this build is a 1977 Chevrolet Corvette C3 chassis that was shortened by 3.5 inches to mirror the original 300SL’s 94.5-inch wheelbase. The frame was reinforced with interior plating, and the front suspension was overhauled with an Aldan American coilover kit, replacement ball joints, tie rod ends, and control arm bushings. A fiberglass transverse mono-leaf spring handles the rear, and stopping power comes from stainless steel-sleeved calipers over ventilated disc rotors at all four corners. This is not a body dropped onto a stock Corvette frame and called a day. The chassis work shows genuine engineering intent.
The 5.7-liter Vortec V8 was rebuilt during the project with replacement pistons, a crankshaft, a mild roller camshaft, lifters, roller-rocker assemblies, and LS1-style beehive valve springs with CompCams keepers and retainers. Induction comes from a Holley Sniper electronic fuel injection unit, which provides modern cold-start reliability and tuning flexibility that a carburetor simply can’t match. The transmission is the real conversation piece: a “black tag” ZF six-speed manual sourced from a 1992 Corvette ZR1, mated to a dual-mass flywheel and a magnesium bell housing.
The hand-laid fiberglass and vinylester resin bodywork was ceramic-coated following the build’s completion. Details include chrome bumpers and brightwork, a glass Sigla windshield, pivot-out door handles, wheel-arch “eyebrows,” and fender louvers with twin horizontal aluminum spears. The plexiglass side and rear windows were made using molds taken from original 300SL glass, while the door hinges, door latches, trunk latch, and badges are all custom CNC pieces based on parts from Herman Quint’s personal collection of original 300SL components.
Inside, the cockpit features low-backed bucket seats trimmed in oyster leather, with a color-coordinated headliner, dashboard, door panels, and sills. Black carpets line the floors and rear bulkhead. A two-spoke steering wheel sits ahead of Speedhut instrumentation, including an 8k-rpm tachometer, a 160-mph GPS speedometer, and auxiliary gauges. Vintage Air climate control keeps the cabin comfortable, and a Holley Sniper EFI controller is mounted on the dashboard.
East Coast Gullwings Mercedes-Benz 300SL Gullwing Replica quick take
The original Mercedes-Benz 300SL Gullwing, produced from 1954 to 1957, is one of the most important sports cars ever built. It was the fastest production car in the world when it debuted, the first production car with fuel injection, and its upward-opening gullwing doors, born from the necessity of its tubular space frame chassis, created one of the most iconic silhouettes in automotive history. That context makes this car all the more interesting. The seller didn’t buy a kit off a shelf. He inherited the tooling legacy of his uncle, Herman Quint, a German-born engineer whose Quint Motorcars replicas were among the most respected in the field, built from molds taken directly from an original 300SL.
