Roofscoop if an MSO option will certainly be 25k or more maybe requiring CF roof panels too or sth alike ... probably the MSO front with louvers will also be a 15-20k option that would be in line with previous offerings ...If I do it, it would have to be with the roof scoop. But then that also means you have a bunch of carbon which frankly I don’t really want. It’s over done. I’d do a kick ass paint job and a roof scoop and that’s it. But likely you will have to spec it over the top to get the scoop.
Other thing I could also see is Senna brake system as cost option and cf wheels ... both of course also not being cheap ...
