bmw warrenty-whats covered?

[shadrack]

Well been looking at an approved use bmw 2010 so obviously under warrenty still with the option to extend (is this offered no matter what the milage) are bushes etc covered?  Also this isn't on an x5 its on a 320d msport convertible.
Might not get another x5 yet after calculating I could save £50 min per week on fuel,  £300 per year insurance, and between £150-£350i on road tax, so all in all I'm finding it very hard to justify needing another x5.  I was always under the impression that economy meant sheds such as prius etc, I manage fine to run my x5 I just really am thinking its a pretty big car for 90% of the time just me!
