Just fixed a few things, and changed others in the process.

Here are some of the things I changed:
Fixed the rear suspension that didn't work and changed the look of it a bit.

Fixed the front suspension that wasn't properly connected to the chassi, due to a piece of it being missing.

Fixed the cockpit camera, now it works perfectly.
(recomend using this command during the gameplay: >>CameraManagerScript..SetCameraFov 80)

Changed the rear window so it fits better.

Changed the position of the seat and fuel tank, increased the amount of fuel, and put 50lb of dead weight so it's a little harder to flip over (it still happens).

Added a little light in the back that lights up with the headlights (Act. group 1).

Last but not least i changed the controlls, now to turn it you use the roll instead of the yaw, I found it easier to control but if you don't like it, it's easily reversible, Just select the front wheel and change it from being activated by "roll" to "yaw" (you gotta do it on both sides)

This little vehicle was originally built by Sm10684 and all credits go to him :)
