The Duntov Turbo was built as a partnership between American Custom Industries (ACI), a company known for building replacement Corvette body panels, and Zora Arkus-Duntov. It was developed as a highly-stylized convertible sports car based on the production model Corvette. Each of the special Duntov Turbo's also came with a turbocharged V8.
As the story goes, when the Corvette ZR-1 came out in 1990, Dick Guldstrand saw an opportunity to create his vision of the perfect Grand Sport ride, instead of his name just getting slapped onto another Chevrolet product. He asked GM for fifteen ZR-1’s and some money. He got one car and permission to do whatever he wanted to do with it. And that’s exactly what he did. Called the "GS90", Dick's car would prove to be the most elaborate and expensive specialty Corvette ever built.
Reeves Callaway has always had a dream of competing a Corvette of his own at the 24 Hours of Le Mans, France. The idea begin with the body work for a street version, but one thing led to another, and a full race version was completed as well. The street version is almost identical to the race version because the hood, tail, rocker panels, and lower door halves, are all made of carbon fiber, just like the race version.
The Chevrolet Corvette Sportwagon was never actually built by Chevrolet, it was an aftermarket kit developed for the C3 Corvette that solved its single biggest problem – the total lack of useable trunk space. When the third generation Corvette was released in 1967 it proved popular thanks to its shark-inspired styling. The one key drawback was the fact that there was no trunk lid, and the small trunk area was only accessible through the interior of the car behind the seats.
In 1989 Callaway introduced a Speedster which was the culmination of their styling, engineering and trimming talents. Their first example was a bright green ZR1, which had a severely chopped windscreen, no side mirrors, eighteen inch wheels and a vibrant blue leather interior stitched purposefully from Germany. Nothing about Callaway’s Speedster was reserved, and this is especially true when investigating the specification. The car had 450 horsepower.
1969 Baldwin Motion Corvette
Various upgrade packages were offered by Motion Industries, for the Chevrolet models included within the Baldwin Corvette partnership. The most prominent of these packages included the SS (425 HP) and Phase III (500+ HP) offerings. These cars not only came with a performance promise, but a guarantee to back it up. All Phase III cars came with a personal guarantee.
As early as the late 1990's, San Francisco based coach-builder SV Motor Company envisioned a car that took the raw performance of a Corvette and refined it with a touch of Italian flair.  Their vision was to infuse many of the design elements found in the Alfa Romeo 8C Competizione (from which the SV 9 clearly drew its inspiration, as well as its name) with a 2009 Chevy Corvette.
