Jesus christ, is there not something in the sale of goods act about warranties having to be honoured for a reasonable amount of time which relates to the original cost of the product and it's use/lifetime etc.
So if you bought a fridge it would be reasonable to expect it to lsat a good 10 years at minimum (my folks have a fridge that's over 15 years old and it's still going strong).
In the case of a car, which cost tens of thousands of pounds and would be expected to cover well over 100,000 miles during it's lifetime I would expect the warranty to reflect that!! Failures at sub 50,000 miles are unacceptable...hell I think anything like this failing at less than 100,000 miles is out of order, especially when they cost over £1,500 to set right.
Stories like this might put me off buying an E92...
