Do these cars exist? The reason I ask that both images are official Chevrolet pictures, which have been photoshopped
That's a good question! Now when you ask, it probably still is a photoshopped Corvette. However, the man behind this company is not obscure at all. The company has a history of building other kitcars/conversions.
Their another product currently is this modified Mustang which is not a smart rendering, I suppose
