FYI - have had the tow bar fitted at the Tow Centre in Bury Lancs last weekend, cost was £362.50p inc VAT for a Bosal swaneck and dedicated 7pin lights only electrics to a 2015 VX insignia 2.0 ltr Sports tourer sri.
Dont think that too bad as was quoted £876.00 +Vat with Vx.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
