Gmod vehicle addons not..... adding.

hi guys. i have various vehicle packs installed, like the mega vehicle collection (i think) and the vmod pack, but they arent showing up in game at all.

a list of vehicle related folders in the addons folder:
DNRC vehicles
vehicle_collection
Vehicle_sound
Vmod.

any help is appreciated.

DNRC = Models, not drivable.
vehicle_collection = Its for the Pre-OB Gmod, outdated long ago.
Dont know about Vmod tough.

i had a vehicle pack working today, but i deleted the gmod folder, due to other problems (cameras not working for one.
