[[XST]O_x]

You've put ; in the end of the public callback,which may cause crashes.

pawn Код:

public CreatePrivateVehicle(pName,id,x,y,z,r,c1,c2);

Should be

pawn Код:

public CreatePrivateVehicle(pName,id,x,y,z,r,c1,c2)

And,pName is a string,so it must contain square brackets at the very least.

pawn Код:

public CreatePrivateVehicle(pName[],id,x,y,z,r,c1,c2)

And,I don't believe you can compare strings within only equal signs,use strcmp for that.

Also,pVehicle is a string,so the variable should contain cells.

pawn Код:

new pVehicle[MAX_VEHICLES][38];

And,another error I found,you should format pVehicle,not define it with '='.
Like this:

pawn Код:

public CreatePrivateVehicle(pName[],id,x,y,z,r,c1,c2)
{
    new v = AddStaticVehicle(id,x,y,z,r,c1,c2);
    format(pVehicle[v],38,"%s",pName);
    return 1;
}

And,you can't create natives just like that,they must be commented.
Therefore you will also need to forward your function.
