The answer of how it got down there, to where it needed a crane to get out

a broken elevator in Turin, Italy, apparently trapped this impeccable 1962 Alfa Romeo Giulietta SZ underground for 35 years.

It was owned by a mechanic who, presumably, was unable to get the car out of the basement, opting to just leave it there for more than three decades. Once the mechanic passed away and there was no will to determine the car’s fate, it reportedly went to government auction this morning, where it sold for almost $650,000

Effectively a super-hot race car for the street, Alfa did not produce the SZ in large numbers. Most estimates peg total production at just north of 200 cars.
