In the production history of Alfa Romeo, the letter E indicated the “Veloce” model of the Giulietta Sprint, however it was not always this way.
If in fact this is true (but with Alfa Romeo you can never be 100% sure) as regards the Veloce of the first 750 series, the subsequent 101 series had the same letter between the chassis number produced between 1960 and 1961, after which the numbering changed and the letter E disappeared. This car in particular has the chassis number with the E in the right place, and it was delivered new to an American living in France.
The first owner (and his wife) owned the car for 24 years and then sold it to the current owner, a professional photographer: the owner often means an unchanged car and in fact the car looks solid and, with the exception of a few details like the upholstery, looks quite correct, including the black California license plate.
