Not as famous as Stirling's other R129, but this one was in danz benz's collection (obtained through H&H aswell to my knowledge) for a long time up until recently where it popped up for sale for I think 40 grand but don't quote me on that!!
^^ Silver ones a bit more significant and lower miles whatnot, so obviously it'd be worth more and probably not comparable in that sense.... Pictures of stirling w this car are on the internet too with articles so the provenance is a bit more significant w this one...
BUT 12 grand is a pretty generous estimate though as that's what nice pre facelift 500SLs seem to be doing these days; maybe more in some cases! and that's ignoring the provenance, which clearly matters..... This'll be a good one, H and H get some really cool cars, mercs especially..
