dealer and getting a towbar

[klberlingo]

just joined the site and have went thro the search option for towbar information. Here's the dilemma... I'm in the last negotiations of purchasing a new 1.6 enterprise off a main dealer. I am trying to get a towbar thrown into the deal as I was able to get an independent dealer to quote for the same model incl. towbar fitted for the same money. Think the main dealer is looking £300 extra or so to supply and fit.

Anyone had this before? dont mind where I go as the indep. dealer has a good enough reputation.
