Problem is that its lease car and I daren't try fitting it myself!
A family friend is a vw specialist and he didn't want to do it for the same reason. Installing the bar is the easy bit. It's the electrics that worry me as if the car senses a voltage drop it puts the car into "limp" mode and you can only do 30mph! Explaining that to my boss would be interesting.
I may try GT towing again, they quoted me the 600 quid for the witter in the first place but perhaps with the westfallia tow bar now available they are worth another try.
