I was there but sadly missed this. I showed up a little late.

 

 

To put some infos in here in the right position:

There were 50 streetlegal cars (those with the rounded rear spoiler), out of those most were painted pearl white with blue. But there is at least one in silver, one in dark grey, one in dark blue and one or two in black. Also there is a rumor of a total white one, but never saw pics of that other than a Maserati prototype that wasn't sold after testing ended.

Then there was the racing car for the FIA GT1 racing series, which was never allowed to Le Mans 24h due to different regulations for GT1 cars of that period in FIA series and ACO races (as Le Mans). I think around 12 of those have been built, but I'm not totally sure.

And then Maserati made a small series of 12 individual numbered cars, called the MC12 Corsa, which were for trackday use only. One of those 12 (the very first one to be exact) was transformed to some kind of street legal use by a rich german customer. You can find pics of that black car with german licenseplates from Munich (M-HH982). It was auctioned last year at Oldtimer Grand Prix Nürburgring together with a white/blue street MC12. Will show pictures of both if you like. The orange car also is a MC12 Corsa and ran on german dealer plates for a while, but never was totally transformed for street legality. It was for a while with a customer connected to Edo Competition, but now is for sale with Gohm in south Germany.

 

Here are the pics from Coys Auction at Oldtimer Grand Prix Nürburgring last year

 

And here a few pics of the orange painted MC12 Corsa. While the black one above is #01 this is #08. Pictures were taken by me in March 2010 in Meilenwerk Stuttgart/Germany at two different days. First pic is in the workshop of Ferrari/Maserati dealer Gohm, the other pics are three days later when the car was loaded on a truck for the "Retro Classics" motorshow in Stuttgart, were it was shown together with a white/blue MC12 streetcar (will have to look up those pics as well).

 

And last few of the set

 

Found those promised pics of Retro Classic 2010 very fast, so here they are. Streetcar is another chassis than the car on Oldtimer Grand Prix, so these are the four MC12 chassis I have seen myself so far.
