Nap, I can only dream of that sort of performance..but we'll keep pushing.
I would do a digital replica of Rolie (in 1964 GT body though, as making sedan bodystyle is beyond my skills right now), but I am too busy ( read interested) making my own very first 3D graphics additions to game. Our team did few year ago Mini Marcos MkI for the gt legends and while it is not bad add-on, we have learned so much about the game and how to make things for it after that, so Marcos definitely needs an update. As the original 3D graphics artist of Marcos has changed his interests and our other graphics guys is busy, It became time to me learn doing some 3D stuff.
I started easy way by making optional / additional oil cooler in front and as it was suprisingly easy (took one night), I pumped up the target "a notch"... And decided to try making original Marcos dashboard for it. Progess is slow (and a lot harder of course), but while it is not anywhere near finished, it does work in game already. Nevertheless, there's still stuff to do, chrome plates behind the instruments, lighter plastic material for the (now too) dark dashboard, etc...
Another thing in PC Simulators is great is the fact that you can run tracks that do not exists anymore. And in most cases you can run them in their golden days glory, like the 1965 Clermont-Ferrand (also known as Charade), in this early preview video of version 2.0 of Mini Marcos for GT Legends: https://www.youtube.com/watch?v=vQ_bIe6Bqko
