I was just thinking when I had just started up a server with the cool half life 2 weapons, when I thought, "Hey, It would be epic if there were some half life 2 vehicles!"
First of all let me just say, yes I have searched for them, and the only 2 things I could find closely remote to them is the stunt buggy, and the air-boat.
The first thing I think should be created is the scout car. Perhaps fire quickly, and deal 10 damage? And should perhaps come with 2 types, one that is normal, and another with the Tau Cannon.
The next thing I think should be created is the muscle car.

Another thing I think should be created is the Air-boat (I know there's one already, but there really needs to be a recreation.) It also should have 2 varients of un-armed, and attached pulse rifles.
Another thing that should be created is a jet ski, one with a machine gun, and another just a jet ski.
One of the last thing's that should be created is the "Hunter-Chopper" That would have a large amount of health, weapons such as a machine gun, rocket's, and an ability to drop bomb's if you pressed the light key.
And finally the last thing that should be created is the Combine's APC. The combine's APC should have a large amount of health, a Co-pulse rifle in a secondary weapon, and should be able to launch rockets.
