Out of date warranty index website

[iloveboost]

A warranty company has an index site with loads of data on it gauging the reliability of new and used cars. The thing is a lot of this data is wildly inaccurate now as it's so old. For example according to their data the average Citroen Saxo has 48K miles and is six years old when a claim comes in! Also according to them it's the eighth most reliable car...in the world!
Now I've come on here to ask why don't they update the data?
I will accept the answer 'because no one cares but you'.
