The Sondergard idea comes from different kit cars and was designed by Jesper Hermann as a “perfect Danish supercar”.
The original kit is from the Opel GT (also known as Pontiac Solstice) and it is a retro car designed as a race car that can accelerate from 0 to 100 km in just 4 seconds. The engine is of 4 cylinders 2.0 turbo with 265 hp. The price is between 38,000 and 65,000 Euros.
I think that’s enough and you should take a better look at the pictures.
