My design inspiration came from several other GT and true sports cars of the 50s and 60s. The first is the 1956 Ferrari 250 GTZ (Zagato). This is an absolutely gorgeous car.
The second is the 1962 Ferrari 250 GT Lusso.
The third is the 1962 Chevrolet Corvette, particularly the rear design which carried over to the C3.
Finally, I was also influenced by the concept VOX 1800 renderings by automotive artist Bo Zolland.
