Vehicle Sounds

Hi,i have been trying to find some good sounds to replace the vehicle sounds with,like the default with something else.

Like the sounds that go into Steam\steamapps\username\garrysmod\garrysmod\sound\vehicles

So,im wondering if anybody has some links or downloads to suggest,i would really appriciate it,since i have been looking from everywhere.
Thanks,

they aren’t easy to find , you need to make them with sound effect generator. or record in real life car sounds.
