‘Muriel’ the Micra started life as a humble family run-around and was bought cheap to do the Preston road rally as a ‘wrecker’ and to be scrapped after that. However she survived and over time was slowly specced up being converted from basic road rally spec, to enduro rally spec and then stage rally spec.
Then after selling my old rally car, I invested further developments in the car with a number of Grp. A modifications.
Here is the specification of ‘Muriel’ at the moment. At the bottom of the page is a list of intended further modifications.
