No...this is not a typo. Many versions of the Corvette were played with in the beginning including one named Impala,,,,,later used on the full sized sedans that took several styling ques from this version.
"Chevrolet came out with this show car, called the Impala. The experimental model used a 5-passenger fiberglass body with the V-8 power plant. It had a 116.5-inch wheelbase and was 202 inches long overall. It was finished in two shades of blue, and had chromed wire wheels with functional knock-off hubs. The bumper and grille were an integral unit, and both front and rear styling resembled the new Corvette."
On July of 1955, the Chevrolet design studio staff create a dream car for the 1956 GM Motorama show, called Corvette Impala. The Corvette grille and grille surround are incorporated, as well as other Corvette components. This hardtop five-passenger sports sedan shows the name "Corvette Impala" on the front emblem and rear license plate. On January 19 of 1956 the Motorama show opens in the Waldorf Astoria in New York City, running for nine days. The 1956 Corvette makes its debut and the Corvette Impala show car is displayed.
Some sources state it was first out in the 57 car show but it was really in 56. After being shown the fate of this model has not been verified but rumors have it that it was scraped, which happened to a lot of the show cars. There was on one produced and it was,like the 2 seat version, fiberglass.
I have requests for 57 corvettes and parts and have some located, just a matter of getting them to me. I am still in need of a 54 Bel Air or 58 Bel Air roof for this. Looking at the photos it looks like I will need to stretch it out in front of the front wheel, the center and the real wheels. I will also have to heighten the body a bit. Nothing beyond my skill set so it should be a rather routine build. If anyone has son recommendations on the wheels please feel free to comment. For this car I will go out and buy the proper wheels or trade for the proper wheels since they are and intrigale part of the overall design. The interior will be corvette all the way since I have no photos of the interior. Again, if anyone has further information on this car please feel free to add it to the thread or PM me.
I will get to this as the parts come in, right now everything is on hold because of the weather. The high humidity does not permit painting and that is where I am on most of my builds right now.
