How do I determine the number of V12Vs made in a given year with a particular exterior/interior color combo? Thanks in advance!

 

The factory is the only source for that kind of detail. Unlikely they'll have it at their fingertips, so unless you've got juice with someone, I don't think they'll bother. But, you may get lucky since they seem to be making some effort to database their last gen cars. You can also try Tim Cottingham at AMOC. He's the Aston registrar. If you do get somewhere, make sure you let us know!
