Here’s an interesting story about a last minute change that never felt like a typo that had me confused while working on the 1956 Mille Miglia project.
Using www.racingspirrscars.com as a semi-official source, shows car 33 as a Renault 4CV.
Our photo does not match. So off to AI and image searching to see if we can turn up some information. Clearly the image is not a Renault. It is a Fiat-Abarth 750 GT Zagato.
