Here is an Italian car-park: Naples Airport.
My casual analysis of the Italian fleet leads me to conclude Fiat, GM, Toyota and VW dominate the low to middle market and thereafter it’s Audi and Mercedes. The losers are Renault and Citroen at one end, Ford in the middle and Lexus and BMW at the top. Subaru, Mazda, Honda and Mitsubishi have no strong presence. Alfa aren’t even all that common.
On the colour front, I note that Italians like white and also have the same preponderance of blacks, greys and light metallic tones. There’s not as much red as in Denmark.
Older cars? Very few now I come to think of it, apart from Pandas. In one village near Salerno I counted the parked cars and Pandas made up a third of the vehicles. You could see four parked in a row with no difficulty. I would have thought the dry climate would mean more of all cars surviving. Of the non-Pandas the older cars were some 90s Alfas, Fiats and Lancias. Did I see an Astra F? No, sadly. No Asconas and no early Lagunas or Xantias. All of those are routine older-car examples in Denmark.
