Thank you to Motorkade's wonderful build, I was able to hover-convert and modernize the original.

If you don't like the color, in painter, choose the top left color block and recolor.

Start the car with AG1.
But before you go racing away, raise the hood with trim to see the pristine 750 hp 4.95-litre (302 cu in) Ford V8 and Borg Warner T8 Transmission.

Okay.
Slam that hood down and pitch up to peel out.
Steer with roll.
Lights are AG2.

....... oh no, a cliff, must, not, stop... . .
AG3 activates flight. (C'mon, I wouldn't leave you hanging.)
Deactivate AG1.
VTOL up is up.
VTOL down is landing.
Steer with roll.
Trim up pitches the car forward.
Trim down pitches the car backward.
Throttle controls forward propulsion.

And geez, if you do happen to get wet while driving this car, keep AG3 on, center trim and throttle up to boat around on the deep blue sea.
To take off from water, you must brake and raise VTOL...Then fly away.
Have Fun.
