Clio has an engine repair

My little Clio has also reached an age and 90,000 miles on the clock. I was alerted by the garage a few weeks go when the speedometer failed, that the distribution kit and all its parts should have been replaced at 72,000 miles. The penalty for failing to take heed might be that the cam belt breaks and the motor would be caput!! I'm sure there is some leverage in the mileage for these things but as we cannot afford a more recent model, little Clio has now been repaired. maybe she will be kind and helpful for the foreseeable future as she has been a good car so far!
