There were only 4 M471 cars that were black. all went to Italy
They were 0587, 0645, 0651 and 1199
I dont have a record of any of them in recent years
However i dont think it is the third series 1199 as that had a sunroof
Interestingly 0645 had zero options listed - not even 220 (limited slip diff) that was on the others and most M471's
There was no mention of a roll bar or red lettering on any of them
I dont recall the exact time that red lettering became available on black cars - some months after lettering started and they realized that the black on black was unreadable. However I understand that all side lettering (apart from on GP white cars) required a special option number and none of the 4 cars mentioned have that
So I would be fairly confident to say that the lettering was not original from the factory
