So much for factory warranties, factory refuses to deal with cracked windscreen. Maybe my choice of enjoyable automobiles needs to be reassessed.
I'm sorry if I'm repeating stuff I've said before- and if you bought the car through a dealer n France, then what I say won't apply - but the primary responsibility is with the dealer NOT the manufacturer.
It goes without saying that as a first port of call you should try negotiation rather than litigation but if you have- and it hasn't worked- the dealer is your first resort. Factory 'Warranties' cannot l;essen or reduce your normal stautory rights.
I say this without in any way seeking to support what is- on the evidence you supply- a pretty blinkered approach from MMC
