SEMA 2024: 1993 Chevrolet Corvette C4 Mercedes Turbo Diesel Swap – Kustom by Keck

The Malaise Era of 1975 to 1985 was a dark time for automotive enthusiasts. With new emissions and safety regulations from the Federal government, cars quickly got slower, heavier, and uglier.

The 1972 Corvette was rated at a dismal 200 horsepower, while the full-size 1977 Monte Carlo was available with a 140 horsepower 305 V8 or a 170 horsepower 350 V8. The era of the muscle car had come to an end, and a new era had begun that was focused on efficiency, not performance.In an effort to increase the average fuel economy of its fleet, General Motors experimented with smaller engines, turbochargers, and other tricks and technologies to get more MPGs.

With so much attention on smog pumps and secondary air injectors, there was one thing General Motors never built: a diesel-engine Corvette. To do so would be unthinkable; it would be a sacrilege of the highest degree. While there were many prototype and experimental vehicles throughout Corvette’s history, no customer cars ever left the production line with a diesel engine from the factory.

However, Tennessee-based Kustom by Keck has transformed his 1993 Chevrolet Corvette C4 Greenwood Edition into a diesel-powered sports car. I saw his custom Corvette at the 2024 SEMA Show, at the Air Lift Performance booth in the Central Hall.The Corvette’s original powerplant has been swapped with a 1999 Mercedes-Benz 3.0L OM606 turbo diesel engine. It is paired to a 700R4 transmission from Transmission Mafia in Gainesville, Georgia.

This is the kind of weird engine swap I would have loved reading about in Grassroots Motorsports or Car Craft magazine back in the day (after reading about V8 S10 swaps, of course).

The Corvette rides on Air Lift Performance suspension, allowing for adjustable ride height at the touch of a button to achieve the perfect stance.The exterior of the car is a visual blast from the late ’80s and early ’90s, and it’s over the top in the best way possible. The car gives serious Miami Vice vibes with its white wheels and teal and purple custom pinstripe graphics.

Kustom by Keck didn’t stop with the visuals, either. This car is filled with unique custom touches, including a standout set of custom infinity mirror taillights from RetroVette, which provide a high-tech, futuristic flair to set it apart from every other Corvette. Every corner of this C4 has been considered, detailed, and reimagined.

In a world full of LS swaps and carbon-fiber everything, this diesel-powered, 90’s throwback C4 show car breaks the mold and refuses to fit in. It’s more Radwood than SEMA, and I enjoy highlighting custom car builders that do their own thing.

This one-of-a-kind car was recently advertised for sale on social media in June 2025, with an asking price of $15,000.

SEMA 2024: 1959 Chevrolet Apache Pickup by Stafford’s Garage

The introduction of the Chevrolet C/K series in 1960 was a turning point for pickup trucks. More than 60 years later, the C/K series is still highly regarded by enthusiasts and collectors. But before that was the Task Force line of trucks from 1955-1959.

At the 2024 SEMA Show, nestled among the heavy hitters in the Toyo Tires Treadpass pavilion, I stopped in my tracks to admire this custom 1959 Chevrolet Apache Fleetside nicknamed “Thunderchief.”

This stunning ride was built by Chris Stafford of Stafford’s Garage. Based in Las Vegas, Stafford’s Garage turns vintage metal into rolling pieces of art. With “Thunderchief,” Stafford has raised the bar for what a restomod can be, blending postwar design with modern materials and craftsmanship.

The Apache’s big window cab distinguishes it from the small back window C10s that followed, but it’s the deep, dark gray metallic paint that pulls you in. The color is rich and lustrous, looking elegant in the shade, but sparkling in the sunlight.

Against this moody exterior, the truck has a full custom red interior. I’m talking seats, carpet, dash, door panels, everything! Bits of chrome accents break up the sea of redness.

Inside, every detail is executed with care. The interior maintains the truck’s heritage with new reproduction gauges and an original-style radio. The red leather-wrapped chrome steering wheel with flat bottom is a modern touch in this classic truck interior.

“Thunderchief” rides on a set of 20-inch Raceline billet wheels. The wheels have a slotted design with a polished lip and are color matched red with silver accents.

They sort of remind me of monoblock style wheels on a Mercedes, but with tri-bar center caps. I think these wheels complement the truck’s smooth body lines and aggressive stance. It’s the kind of setup that says this is a show truck, but it can still haul stuff if needed.

One of the standout features of this build is the flawless chrome work. Every piece, from the bumpers to the trim, is polished to a mirror finish. The side of the bed has beautiful chrome and red trim pieces that just work on a 1950s era truck. It’s the kind of meticulous detail that separates good builds from great ones — and “Thunderchief” is firmly in the latter category.

Among the thousands of vehicles at SEMA, only about two dozen have the honor of getting invited to the Toyo Tires Treadpass pavilion. This area houses a curated group of elite custom builds, any one of which could be on a magazine cover. This Apache pickup certainly deserved its place among these special vehicles.

I will keep my eyes out for more vehicles from Chris Stafford and Stafford’s Garage in the future. The craftsmanship and detail shown in “Thunderchief” really shows what they are capable of building, while staying true to the spirit of the original truck.
