[GH85Carrera]

This Iso Isetta raced in the 1954 Mille Miglia
It was the first car to leave the starting line at 9:01pm (thus the "2100" number) on May 1st and the last car to cross the finish line 22 hours, 10 minutes and 2 seconds later the next day.
For those wondering, drivers Domenico Stragliotto and Adolfo Montroio came in 177th place.
