I’m sure you can PM some painters to see if they’re interested in recreating this. I don’t recall ever seeing this one unfortunately.

the aston is my favorit racing car ant that livery is my favorit, it was i forza 3 and forza 4 but sadly i have not seen it in forza 6

No it’s not. I’ve tried to do that one some time ago, but couldn’t find sufficient source photo’s to do a replica.
