Umm you mean this?

pawn Code:

if(!strcmp(cmdtext, "/respawncars", true))
{
        for(new i = 0; i < MAX_VEHICLES; i++)
{
        new name[24], string[64];
        GetPlayerName(playerid, name, 24);
        format(string, sizeof(string), "%s has respawned the cars", name);
        SendClientMessageToAll(color, string);
        SetVehicleToRespawn(i);
        }
        return 1;
}

EDIT: Beaten to it again -.-
