Strange. The Nardi-Danese Marco was the subject of Puzzle #1786 and looks completely different. All I could find on the Net refers to that car, dating from 1947 or 1949 (the answer to the puzzle).
I'm not 100% sure that the car I posted and the Autopuzzle car are one and the same, but the only differences between the 2 cars that I notice are the paint color and the hood ornament. 2 things that are rather easy to change. So my guess is that they are 1 and the same car.
If my information is correct, the wheelbase of the car is 25(6?)30 mm.
About the different bodies between this car and Puzzle #1786 gives my source (not the internet) the following explanation:
Al Circuito del Monrenero, disputato a fine agosto a Livorno, esordģ, con al volante Enrico Nardi, anche la 8 cilindri 1500. Questa vettura, anche se reclamizzata solo sol secondo numero di "Interauto" del 1948, venne
trasformata in un lussuoso cabriolet a quattro posti con carrozzeria Bertone per Marco Fabio Crespi, detto Rudy, e dal nome del proprietario derivņ la denominazione di Nardi-Danese Marco.
Lousy Google translate translation (but the essential part is understandable):

At Circuit Monrenero, held in late August in Livorno, began with Enrico Nardi steering wheel, even the 8-cylinder 1500. This car, even if only advertised only the second issue of "whole" of 1948,
was transformed into a luxurious four-seater cabriolet with Bertone for Marco Fabio Crespi, Rudy said, and the owner's name was derived the name of Marco Nardi-Danese .
