There isn't much you can do unless you are a script god, or you can simply replace the front of the vehicle, or you can actually just replace the vehicle, but it'd have to be transparent, so near impossible, pretty shitty.

@eshenk Was wondering WHERE the main vehicles were, maybe not clear enough for you.

Looking onto replacing the main 3 vehicles with something more, "better" Thanks.

and if had enough time, Please make the bomber jacket to be a bit more longer?
