The original model is displayed in the LEGO idea house located in Billund. It's built by Kjeld Kirk Kristiansen back in the 60's and was basically inspired by the british sportscar manufacturer Lola.
This is my interpretation of this nice model. The first part to be changed was the rims. I've gave the car some wheels which are fitting better to a racing car. To let the car look more modern, I've made the surface nearly studless.
To let the car fit better to my existing ones, I've slightly shrinked the overall dimensions. It's a really awesome car.
