Everyone who plays Garry's mod should know Sakarias car mod where you can change Color of your car, Speed of your car and wheel type.
Making this mod to blockand? Yes, i know you can change color, But speed and Different wheels.
I know you can use "Few" Console commands to change your wheels and vehicle speed, but
Making a GUI for it makes things easier for Newbies, Even if some one works hard on it he could make you able to change Other parts than Wheels of your car, Or even ability to switch Seat amount of your Jeep.
