Hi Nigel,
Love the cartopping photo. My initial impression was Morris Marina, but I seem to recall you might have said that's actually a Saab. Is that right? My uncle, who was an architect and had an eye for design style, had a Saab 99 for quite a few years about then. The recessed door handles ring a big bell but I can't quite connect it.
Anyway, here's 2631 (Groovejet) leaving Andy Paterson's premises in 1986. I'm not sure if the 1980's motoring design icon belonged to Andy or the new owner though:
