Always a crowd favorite when it appears at Laguna Seca is the mighty 1973 Sunoco Porsche 917 / 30 # 6 as driven originally in Can Am by Mark Donohue.
It has gone up slightly in value since it first appeared in 1973 as seen in this photo as Roger Penske watches his team prepare the car for Mark Donohue. (Note the mechanic sitting on the grass with a trusty "Sears" Craftsman tool box nearby and tools etc . laid out on a cloth.
Imagine working on this car today in those conditions !.
The same car in Sept. 2018.
Beautifully maintained.
The last 4 photos were taken by John Adams.
