Not much really; the sparks plugs went after 3 years, but apart from that, nothing else has gone wrong.
The car has done a lot of miles without anything going wrong. It has gone from Reading to:
Essex - 3 times and back
Bedfordshire - 5 times
Amsterdam - 1 time
Dover - 1 time.
And it went from France to Holland.
And this car is very economical!
Essex isn't that far from Reading! If you're impressed with that, you are easy to please. My 140,000 Volvo regularly goes from Reading to the Highlands of Scotland, To and around Belgium and tours around mainland Europe including France, Netherlands and Germany. I would never expect it to fail me. It sounds like you actually expect the Ford to die and just surprised it hasn't!
