They are a great car! Mine is 2006 and just about to hit 84,000kms, so still has a bit of life in it yet.
Ive decided against run flats, but will stick with the stock setup of 225/45/17 and 255/40/17.
So far have received a quote for Nankangs but not really sure what else is out there at a similar price point. Anything around the $500/600 mark per tyre is feels excessive given the age and value of the car...
