The design of the cab and artwork look great!
I don't care for the gauges mounted to the side (but it's your cab).
Unless there's room above the steering wheel, I think it would look better without them.
Or maybe you could build a dashboard with the speedometer on one side of the wheel and the tachometer on the other.
I dreamed of Ferrari parts too, but I think my whole cab cost less than a Ferrari gas pedal.

Every computer based driving cab should have Nebula's Sega Model 2 emulator!
