I need help, i've been looking all over the place to find a carspawn script, i need one that spawns a car for you (where you are) and if you spawn a new car the old one gets deleted and respawned or warped to you, also when you log off the old one dissapears, have tried it myself but couldnt make it work, (the farthest i have come is spawning a car but you steal someone elses XD)
So please help me locate this.
Thanks in advance!
