Oh, and that reminds me, Big Bro who had to go without aircon for several months last year in his brand new S Class due to lack of availability of parts for the unreliable PoS was finally offered £500 off a new Mercedes Benz as a goodwill gesture for the inconvenience.
He took the option to tell them to shove the money up their jacksie. And has since handed back the car as the lease expired. Needless to say, despite his inability to learn from mistakes*, he has not gone for another Merc
* He bought a Mk2 Grandad 2.8 Ghia back in the day. Kept driving it even though the petrol gauge read empty, because the low fuel light didn't come on. Obviously the inevitable happened. Next tank, he did exactly the same, waiting for the fuel light to come on, with the same result
