1983 Corvette C4: Only One In Existence

  

1983 C4 Corvette

Summary

The Corvette that technically never happened: GM built 14 prototypes and 43 pilot cars for the 1983 C4 Corvette, but none were sold to the public.

Only one survived: The surviving car was #4 off the Bowling Green assembly line, making it incredibly rare—but technically not a 1-of-1.

GM wasn't ready to release it: Engineers found plenty of quirks with the new chassis, body, and other systems. Instead of rushing the new C4 to market, GM decided to hit the brakes.

Goodbye, T-tops: GM also decided the original T-top design wasn't the way forward and developed the targa-style roof that appeared on the production 1984 C4.

The others got crushed: After testing, GM ordered the 1983 cars destroyed—the normal fate for experimental vehicles that weren't going to be sold.

But somehow, #4 escaped: Nobody knows exactly how this particular Corvette avoided the crusher. There are several stories, but the real answer has been lost to time.

It was found by accident: About two years later, the Bowling Green plant manager spotted the dirty, beat-up Corvette sitting around the plant property. Checking the VIN revealed what it really was.

It got a second chance: The plant cleaned it up and gave it a red, white, and blue paint job before eventually donating it to the National Corvette Museum.

Restored to its roots: The Corvette was eventually returned to its original white exterior and blue interior, along with its original configuration.

A very important Corvette: The 1983 C4 became a showcase piece at the museum and a reminder that sometimes not building a car can be the smartest move an automaker makes.

Bottom line: GM could have rushed the C4 onto the market in 1983. Instead, they crushed almost every one, fixed the problems, and launched the 1984 C4 as a much better car. Somehow, one escaped the crusher—and became Corvette history.

Most people don't know that there were any Corvette C4s built for 1983, but there were a few (none sold), and there is one survivor that resides at the National Corvette Museum in Bowling Green, Kentucky. 

For the people who do know it exists, they often refer to it as a 1-of-1 Corvette. But this is not true because, altogether, there were 14 prototypes built and 43 "Pilot Cars" built, which were going to be sold to the public. The surviving '83 Corvette was #4 in the bunch that rolled off the assembly line at the Bowling Green, Kentucky, Corvette Plant. 

What Happened to the Other '83 C4? 

General Motors, Corvette executives, engineers, and designers decided that with all of the quirks of the new frame, new body style, and all the other things that still needed more engineering adjustments, the new generation just wasn't ready to be sold to the public. 

They also decided that the original T-tops weren't the way to go. They wanted to design a targa top for the Corvette because it would be more appropriate to keep up and compete with the design of the European sports cars.

After testing the Corvettes at the GM Milford proving grounds, all 1983 C4 Corvettes were marked for destruction. It's a common practice for automotive companies to crush cars they have no intention to sell to the public. 

GM brought in their car crusher and got to work turning the test Corvettes into hunks of metal. This is where the story gets dicey. No one really knows how this #4 1983 Corvette with the VIN # 1G1AY0783D5110023 survived, but one of the stories is that someone hid the Corvette just to keep at least one left around. 

Another story goes that the work crew ended their shift, and the last remaining Corvette was simply going to be put out of its misery the next day. Fortunately, for the survival of this piece of history, the compactor was picked up early and taken away, leaving the #4 1983 Corvette forgotten about.

There are more than just two stories, but we would all just be guessing as to what the true story is. But the story of how it was found is quite frank. Two years after the crushing of the '83 Corvettes, the Bowling Green Plant Manager was poking around the car lot on a different mission and found the out-of-shape, dirty, run-down '83 Corvette on a fluke. 

Not knowing exactly what the sports car was or why it was sitting there, the Corvette was pulled into the plant, and the  VIN # was cross-referenced with meticulous records, eventually revealing its true identity.  

Bringing The '83 Back to Life

The guys at the plant cleaned the Corvette up and gave it a red, white, and blue paint job. The Corvette stayed at the plant until 1994, when the National Corvette Museum was built, which was built right across the street from the famous Bowling Green, Kentucky Corvette Assembly Plant. 

Realizing how important the Corvette was to Corvette history, it was eventually donated to the Corvette Museum. The decision was made to repaint the Corvette back to its original white body color with the original blue interior color, and everything else was restored back to its original condition according to records. 

The '83 Corvette became a showcase for the grand opening of the National Corvette Museum, especially since most people didn't even know that they ever existed. 

The 1983 Corvette leap year is said to be one of Corvette's best decisions. They would have put a vehicle on the market that had massive changes for a new generation, but still needed a lot of work to get it perfect. 

When the 1984 Corvette was introduced, it made a big splash in the market, and everyone enjoyed the new look, sophisticated suspension, stiffer chassis, and the many other upgrades that came along with it.
