If Concrete's thread about models' reliability refers to a certain 'Index of Reliability', then I went and had a quick (refresh) look.

Some of it IS a bit odd though - I mean, I wouldn't have thought there were vast numbers of Chevy Kalos and Tacumas running about - maybe their owners don't make claims because they hardly ever use their cars?
Similarly there's not many Rover 25s about these days.

But I did note that the No. 1 worst score was for a BMW M5.
The bad scores for prestige vehicles will be strongly swayed by the extortionate prices charged for parts and labour for these cars.

In fact just the other day I heard of a chap I know who's recently got a 2015 M5. Subsequentlly, just out of idle curiosity, he'd been looking at the prices for replacement brake pads.

For a set of pads for the front axle (just the pads, no fitting), it appeared it would cost £500 even for ones sourced from eeebaigh.

Just what, exactly, are those pads made out of, that makes them cost that much?
