Dug out some old 'Rally Sport' mags today to refresh my memory. The only information I can find is that Llewellin did compete and finish third on the Cyprus rally in 1988 in his coupe quattro 44 XMN, painted up in 'Rothmans' colours possibly as a one off for that event only. He was the outright winner the previous year in the same car when it was still in it's 'Gemini' colours.
Scanned some pictures, apologies for the poor quality:
