I owned one for nearly 2 years.
You would have to be driving like a compete idiot to get 5k out of a set of front tyres. I was getting around 9k out of the fronts, could have got more with driving a little more carefully. It stings come to tyre purchasing.. budget for at least £120 for a decent tyre due to the strange sizing (you can fit 225 though as I did on my last set).
It's a really good car - it accelerates ferociously in any gear - it really is very quick for a hot hatch. Handling is decent enough, although feels slightly less connected than its main rivals (Focus ST handles much better strangely!). Its a very harsh ride also.
However, its reasonably dull to look at (some may like this) and I found it quite hard to stomach paying £400 a year for road tax - although its not that much more in the grand scheme of things, it just annoyed me.
Servicing is reasonable, around £140-£220 for your services. However, needs to be serviced every 9k, so a bit sooner than most of the hot hatches.
Interior is comfortable and a reasonably nice place to be, although plastics are quite hard. Half Leather sports seats are great. Standard BOSE stereo is excellent. Lots of extras as standard (I believe cruise control wasnt fitted to models before the end of 2007 - check before purchasing).
I was getting around 250-300 miles out of a tank.
Overall, very nice car and a good all round package. I fancied something a bit different and went for an FN2 Type R, which obviously feels slower but has far better handling/economy and feels a lot more fun to drive.
Any more questions feel free to ask!
I find that hard to believe unless you're driving like a bat out of hell everytime you're in the car. Source?
