Carframes for making a easy engine car

Hey guys. So, i have been working a lot of stuff in gmod right now (bored to mention), and i would like some cool carframes to make a easy engine car. Would be AWESOME if i could open the parts of the car frame etc front and back - engines, car battery in front, in back fuel, and somewhere in the car a slot for the fuel taker.
Cheers
