Nothing. In 8 years the car is perfect.
This car is stunning.
Not quick, but holds the road as well as anything I've driven, and despite the height of it, it doesn't roll in the corners.
Other than the obvious tyres and filters, I've not replaced a part on it.
My entire family have Yaris' and they're ultra reliable. I still won't be swapping my Focus though.
My Yaris is perfectly reliable also. I have no reason to change it... other than I would like a diesel (Yaris) and therefore benefit from £35 tax!!! and I would really like AIRCON!!!
Great little car... Highly commended.
