Reviving this thread after a year! Dan Morgan is continuing to post 80's Donington ETC round pics on Flickr, and has reached 1985- including the BTCC round held at the same meeting

I still haven't totally got my head round the question of which of his two Starions (and which race number!) Dave Brodie used at which round, although these pics confirm he ran the #6 car at Donington.
My current theory is that he used the #6 car early-season, and swapped to the #5 car later in the year- I suspect the change came around the GP support round, as a pic of the two cars from the Autosport report announcing Vern Schuppan's GP meeting drive a week or two before the GP shows Brodie with the #5 car and Vern Schuppan with #6.
