Hi,
I've just been on the phone to my local RAC approved Repairers garage in York to book in a service. They said last service they noticed I would need a new timing belt after 80,000 miles or when the car is 4 years old. I've only done 62,000 miles but the car's 5 years old now so I decided to get it changed. They've told me for the new timing belt, water pump, service and labour, it'll be just short of £450.
Not too bad considering the service will be £100 and much cheaper than a new engine would cost! It gets replaced a week on Sat and I'm glad I've spent a little extra now to know it should be fine for another 4 years.
