There is no such thing as a Hover Car for GTA IV. It could be a mod or someone has told you false information.
No, there is not a Ford Mustang in GTA IV. You can mod your car using a computer to get a Mustang but otherwise there is not a Mustang in GTA IV.
There are Pay N Sprays in GTA IV, but they will only change the colour of a vehicle. There is no equivalent of Transfender, as in GTA San Andreas.

1) You can't get an Airplane in GTA IV. 2) You could mod one of the helicopters into a Plane (PC version ONLY) 3) You could buy GTA SA, you can fly planes on there.
