Seriously disheartening.
The whole windshield dabacle is just nuts. It's been happening on other models too, 12C, 650S. And now a ton of them on the 720, 570 and 600. Not just a car delivered with a bad windshield, but cars going through several bad windshields one after the other. Not just windshields too, but the sunroof panels on the 720s. And you're lucky if it shows up right away, some guys get some miles before they crack. It's all speculation, but it sounds like it's a fitment/chassis issue and not a glass issue.
Then there have been several aftersale/warranty horror stories like that. I'm not an aftermarket parts guy, but for little shit like exhausts that is ridiculous. They should be bending over backwards to make clients happy.
Finally, the cars that have burned down, and the subsequent treatment of their owners, has been really sad to say the least.
I considered myself a pretty big mclaren fan, but I don't think mclaren ownership is going to be anywhere in my near future. Hopefully in a few more years they'll have the kinks worked out, who knows.
