No don't go to fords!!, the number is from my buds firm, the glass is made by AUTOGLASS, with 1 year warranty.
A remove and refit with SEALING is £40(cash), but if ANY chips it WILL crack!!
I would just shop around, then bater them off one against the other, keep the details as they will ask who you spoke to etc to get that cheap quote!!
