Maybe I should throw in an old one I found..... taken I believe at the 1974 World Cup Rally. Obviously a Bentley and driven by the eccentric (and sadly, the late) Keith Schellenberg.
Apologies for the quality, not really appropriate in the quality contributions of others but I recently found the photo in my old damp garage where it had languished in a cardboard box for 35 years, with damage to the colours the result. So I dried it out and scanned it..... just thought someone might be interested.
I seem to recall the rally started in London and did a special stage 'somewhere in Surrey/home counties' where I took this photo. I think the cars were en route to Southampton to get the ferry to France.
Edit... sorry Bob for the size.... I tried to post it as a smaller thumbnail but when I originally posted and clicked it it wouldnt enlarge so posted it slightly larger.
