This BMW 502 is standing on a scrapyard in Switzerland.
Although only 23000 examples were built between 1952 and 1964, the "Barockengel" was, just as the 507, important for BMW to find it's role in the car market after the war.
Nowadays, this model is so rare that even in the condition of the pictured example a restauration could be worth consideration, as good examples cost about 50000€.
After such a treatment, the now abandoned car could look like that one again:
