Memories of porshe company

About 40years ago.
We had the international autmobile license.
Germany from Nice to have used a high-speed road .
There was no speed limit Autobahn,AutoStrada.
There were few cars on the road.
It was a smallcar Fiat-500 most.
Please think small car of Japan today.
They were running at about 80 KM.
I feel the history of the relationship and life car in daily life.
Our car was a Benz,But maximum speed was 160Km meter.
We are have been Welcome guests Who come from Japan because
it was less at the time.
One by one ran on a Test-Course of porshe-Companny.
The car was a 2200cc air-cooled old.
He was the basic reason is taking the Course entering the Corner
from the top speed. (160Km?)
The driver was a mechanic in the Company.
but taking the Couse of the drive was a professional-looking.
They were advertising a turbo car of new development.
Thank you.
