It is easier to read if you post all the pictures and links in one post Koenerman.
This car was driven by Gerry Marshall who many regard as one of Britain's finest ever drivers and tuned by the great Bill Blydenstein. I remember when the "super saloons" was a popular race class in the UK - 5 litre V8 powered special saloons - and have happy memories from seeing this car compete at Brands Hatch. Thank you for posting this great car.
