Thank you indeed, and good to see your dad in the middle of such an internet buzz!
I bet he would smile.
Also had a copy of the Humberstone advert sent to me today dated March 27, 1986.
It is clearly a 'liquidation' advert with the Lola and Hart engine and the original suspension all being sold with lots and lots of other bits n pieces.
£10,000 for the car with engine!
the twin carb'ed Pinto engine is there too, the one fitted to the car when Mr Wilkes restored it for intentions to race in ThunderSports.
