Car spwn problem

On Gmod 10, when i try spawning a car like GMOW and VMOD cars they spawn out but are invisible so when i use the phys gun i can grab the car and put it down but i try to get it that i can see the car and get in. But when ever i get in all i see is a white screen and i was some where under the map, when i try to respawn with console all i get is a blank screen and it is all messed and you can’t even get back out the car and find the actual land.:frowning: PLZ HELP

They don’t work anymore due to recent updates.
