Thanks for all the comments.
I dont reall think that I drive that spirited to be honest. Don't really have the opportunity in and around London, and certainly when my better half is in the car with me.
However, only yesterday I noticed that the computer was telling me I needed a service in 9000 miles. Went into the vehicle status menus on the computer and it's telling me that the rear pads need replacing in 9000 miles!!! Fronts, FYI still have 24000 miles left (they have yet to be changed from when the car was purchased new).
Now this raised the question: given that I only changed the rears pads a week ago, can I really only have 9000 miles left in them?
Raven333: rears tyres are pretty much at the limit now and I will be looking to replace them in the next couple of weeks.
