Did anyone install the tow hitch on their E70? Just came back from the dealer, and I'm a bit disappointed that it does not have the 'hole' for the hitch like my 2002 X5. Sales person checked with the service guys, and they told him that they would have to cut the bumper in the order to install the hitch. They use the kit for the hitch install which, they say, was designed by BMW, so it would look like it was factory made. Anyway, my question is if anybody has the hitch installed, and if you could be kind enough to post some photos. Thanks!
