Photo taken on the starting grid of the 1972 track race of Tatoi - part of the 20th International Acropolis Rally.
Those years, the (remaining...) competitors of the Acropolis Rally, after completing the 4 day- 2000miles cruelling rally, had to enter a track race (to prove they were still fast enough?).
Behind the 510 is the very futuristic NSU Ro 80 a car that was years ahead of its era. Ypu can also see a Volvo, a BMW 2002 and a Peugeot 504.
