Not sure if this will be too late for the original poster or not, but might help someone in th future anyway. I fitted a towbar to my 2.3 Galaxy, it went on really easily. One thing that I did was to get a vehicle specific wiring kit, this made fitting much easier because most of the connections can be made by simply unplugging the connectors on the back of the rear light clusters, and then looping through the wiring kit. On the kit that I had I think that the only thing I had to do was to break into the wiring for the rear fog lamp, so that it could be suppressed when towing.
