C3 Corvettes are not rare, but documented period widebody conversions are a very different story. This 1976 Greenwood Sebring GT Corvette is described by the seller as one of 22 built in 1976 by Mancuso Chevrolet and is documented by a 1984 appraisal and bill of sale. Located in Sevierville, Tennessee, this Corvette is now offered at auction with a reserve.
The car features a Greenwood widebody conversion and is identified in the appraisal as John Greenwood #1005-76. According to the seller, the appraisal references the custom-fabricated body, turbo engine, BBS wheels, and a build/sale through Rick Mancuso Chevrolet for approximately $16,000, with a listed 1984 value of $16,500. The car was reportedly originally white with a red interior and now wears red paint over a Saddle leather interior with red accents. The seller notes that the seats show a few small scuffs. Underhood photos show an Edelbrock water injection controller and multiple holes drilled for additional cooling.
Given the wild looks, you might expect to find a big block in the engine bay, but this car packs a 350-ci V8 crate engine paired with a 4-speed manual transmission. The engine is fitted with Vortec heads, roller lifters, a GM low-rise aluminum performance intake, a 4-barrel carburetor, headers, dual exhaust, Turbo mufflers with chrome tips, and various chrome accents. It might not be the most powerful V8 GM has ever offered, but it should still be plenty powerful to be fun. The seller states that the car runs, drives, and rides nicely with no issues.
The exterior has the unmistakable wild looks of a Greenwood-style Corvette, with flared bodywork, a low stance, and dramatic proportions. The paint is described as shiny but older, with some cracking visible. The seller notes that the panel alignment and gaps are nice and that recent attention included door adjustment, suspension alignment, replacement of trim items such as the door handles, and the addition of new wheels and tires.
Equipment includes power steering, tilt/telescoping steering column, power four-wheel disc brakes, power windows, headers, dual exhaust, and working gauges. Air conditioning is present but currently inoperative. Both the original T-tops and the installed glass T-tops are included. Also included are receipts from prior ownership, a new-in-box Holley Sniper 2 system, and an in-tank pump/filter/fuel gauge sender setup. That gives the next owner the option to continue enjoying the car as is or improve its drivability with modern fuel-injection components.
This Greenwood Sebring GT Corvette will appeal to a very specific buyer: someone who appreciates period C3 customs, documented widebody conversions, and the connection to Greenwood-style Corvette history. It is not a concours restoration, but it is a running, driving, documented, period-correct widebody Corvette with a 4-speed manual and the kind of styling that is sure to draw crowds. For the right enthusiast, this 1976 Greenwood Sebring GT offers a rare chance to own something far more unusual than a standard C3.

Took the beautiful lines of the Corvette…..and ruined them.
Only good thing about this Corvette, it’s a 4 speed.
Like it but would love it with a big block and side pipes, just my taste obviously
John Greenwood did not design this body to look pretty, he designed it to go 200 mph at Lemans with the least amount of drag while covering huge tires.
That makes it no less hideous
We were there in ’76 when he brought the car to Le Mans. Blinding fast but only lasted a few laps when the right rear tire blew and wiped out the fuel cell, which they didn’t have a spare of.
I saw Greenwood race his booming loud Vettes several times to good success. Likely the most patriotic appearing Corvettes ever to hit the track too.
John Greenwood. Unsung hero
This one looks really nice! It doesn’t look as wide as some of the other Greenwood Corvettes that I have seen so it looks a little more agile on its feet. Pretty wild looking car and will definitely stand out wherever you go! Looks like it was built very nicely! I still remember seeing my first Greenwood Corvette in a old car magazine in the 80s and I remember that it was called the Grim Reaper. Looked fantastic! was either black or a very dark green. Look like something Darth Vader would drive.
I understand why these body kits existed: some people wanted their car to stand out in the crowd, and these kits achieved that.
However, to me, they don’t stand up in today’s environment. The main reason being that the C3 design itself was so beautiful that has stood the test of time, and is more desirable than the looks of the kits.
I recently learned that John Greenwood was the innovator and designer of the “box” rear fender and is credited with being the first race team to use them. As odd as they appear anyone who follows sports car or sports sedan racing sees that design used around the world by major teams and manufacturers. That’s pretty amazing to me.
sure, have been a lot of clownvettes lately.
I like the car!
Mancuso Chevrolet. Isn’t that where the “Family Truckster” is from?
So where is the turbo engine? Inquiring minds want to know! And what are the specs on this engine?
Clowns calling a Greenwood hideous, renders their opinion irrelevant.
Negative people make negative comments. Mostly they don’t bid or further the hobby/industry. If you don’t know the rich history of Corvette racing and the huge contributions that enthusiasts like John Greenwood made, then you might be wise to do a little research. 220mph on the Mulsanne straight at Lemans is still legendary today!
I took this Sebring GT to both the Corette Expo and the spring Rod Run here in Pigeon Forge. Everyone I talked too had never seen a widebody C3 in person. I posted some of the history on the car. Lots of people wanted to know more, including younger people. I can say that more people were interested in this car than most later models.
The engine is a GM crate motor, 350 330hp, Vortec heads, roller cam and lifters, low profile aluminum GM intake, with headers, dual exhaust and turbo mufflers. The transmission is an M20. It runs great and starts every time.
Included is a Holley Sniper 2 fuel injection kit and a Holley in-tank fuel pump, filters, pressure regulator, and gas gauge sending unit. I was going to install these on this car, as I have already on a ’68 flared Vette and a ’77 Eckler’s Can Am Vette that I own. Throttle response is great and the fuel economy is much better.
If you want a ‘Vette to take to a show and Cars and Coffee, or just to drive and see people smile and wave, then this ‘Vette is a reasonable-cost head-turner and conversation-starter.
All comments are welcome and I didn’t “ruin”, it. I bought a piece of Corvette history that most people enjoy seeing and talking about. Steve
Steve, Just curious if the brake system or chassis were upgraded? It would be a fun track day car to run that’s for sure.
Some of the earlier Sebring GTs had upgraded suspension. This one does not. And the brakes appear to be stock. On my other C3s I installed Eckler’s “gymkhana” suspension including springs, sway bars, and shocks. In general I cut one coil from the front and installed longer bolts in the back. This provided a good ride with improved handling.
Gotta say I am obsessed with this car. This is my dream car I really hope I can win it! If not, best of luck selling her!! Don’t listen to all the hate haha.
Thanks for the comments. I’ve heard the negative comments in person. But….if you’ve ever parked a real widebody next to a stock Corvette, it’s striking how good these look. Also note that a C3 is the same basic size as later gens, but also lighter! So if anyone thinks this is a “bloated” version of a Corvette, I would have a different idea (to say the least). Take it on a drive or to a show and you’ll get lots of positive comments. “Where are you going to find another one?!?
This is a great-driving Corvette that gets a lot of positive attention wherever I drive it. Plus it is a documented piece of Corvette history. If you know, then you know. Steve
