Another mystery Mini derivative and yet another autocross Special. No information is known about this one, so feel free to help with anything. People, location, details. All I recognize is the A-series engine and the Dunlop wheels. Most of this autocross Special is also still shrouded in mystery, as is this one and this one...
UPDATE 21 January 2021: Correct picture source now added. Have a look at Jalopydays for much more pictures like this. Thank you Shirley for allowing me to use it. The car is not an autocross racer but an autograss racer.
A Mini based autograss Special, somewhere in the UK in the late 1960s / early 1970s
