Slightly unrelated, but still on topic for high mileage Fiat 500's...
After having our 2 Fiat's for over a year and a half, our next door neighbor came across the street, and asked us about the car.
She said she loved the looks and was thinking about replacing her very aged, and very worn Subaru with a new car, since she was planning on retiring in the near future.
So my wife and I took her to the Fiat dealer, and the two of them took off for a test drive while I waited in the dealership (I wasn't feeling well, and spent most of it in the bathroom).
I think it was nearly an hour later when the two of them returned with the car they took for a test drive, and they were talking non stop about how thoroughly lost they got in the neighborhoods behind the FIAT dealer, and it took that long to find their way back.
Well, our neighbor wound up custom ordering herself a '13 Pop, and after 10 full years, just a few weeks back, she sent me this picture:
