There are many issues with it. Having "i" twice and increasing "vv" and then using "ii" which are both undefined symbols.

It will also remove (if you fix those I mentioned above) the vehicle if the player with ID 0 is not in that vehicle.

Vehicles starts from 1, not 0 and you should use foreach to reduce the times the loop for the players gets called.

CMD:removeucar(playerid,params[])
{
    if(PlayerInfo[playerid][pAdmin] < 3 && !IsPlayerAdmin(playerid)) return SendClientMessage( playerid, -1, "You Must Be Higher Level To To Use This Command");
    for (new v = 1; v < MAX_VEHICLES; v++)
    {
        if (!GetVehicleModel(v)) continue; // vehicle does not exist, skip the players loop
        if (!IsVehicleOccupied(v)) DestroyVehicle(v);
    }
    return 1;
}

IsVehicleOccupied(vehicleid)
{
    foreach(new i : Player)
    {
        if (IsPlayerInVehicle(i, vehicleid)) return 1;
    }
    return 0;
}
