Towbar fitting

Hello everyone.

I am looking for some advice regarding the fitting of a towbar to my Superb MkII Estate please.

I have seen on various owners groups etc that people's experiences of having a towbar fitted are wide and varied, and that some vehicles come "pre-prepared" for a towbar being fitted, with some of the electrics etc bring in place ready to connect into.

I have also seen that if towbars are fitted by places which don't really know about the Superb have made real hatchet jobs of cutting into the bumpers and messing up the parking sensors.

Could anyone point my in the right direction to establish if my car has the pre-prepared kit on it, and how to avoid a bodge-it job of the fitting, maybe even suggest a known and trusted fitting company who operate in the North West area?

Many thanks

Mark
