Had a stone hit the QP screen 3 months ago and rang my insurer AVIVA. they put me through to their screen department 'Autoglass' who said they had to source the screen through Maserati anyway so why not go to them to do it as they are petrified of damaging the car and trim knowing the replacement cost and the precious nature of the owners (charming).
I rang AVIVA and told them this and they immediately agreed I should take it to Meridien and allow them to do it, for me to pay and send them the bill.
All done £1660.00......sent them the receipted invioce and got a bank transfer less £75.00
