Hello!!
First I want to congratulate Reiza by the magnificent work he has done with the GSC.
I found a small bug in the F3´s cockpit.
Some cars do not show in cockpit the AIM display.
Not a bug - there are two cockpit variants. One has an open top steering wheel with the Aim/MoTeC-style display mounted to the dash, the other has a Pi display integrated into the steering wheel. You'll notice that the cockpits are textured slightly differently too, one has padding while the other is bare carbon. I guess this isn't so obvious when you disable the steering wheel
