We had a 52 plate classic 1.4 petrol with 120,000 miles on it without any mechanical problems but sold it recently due to worn steering bushes (big costly job)
Other than that it was robust but interior trim can be flimsy especially around the seat edge.
1.4 was a bit weedy but ok in the real world. probably got 40mpg generally.
It did the commute from Wigan to Manchester every day from 40,000 (mileage when we got it) until the day we sold it. Pretty hard miles indeed so it did well.
We also took it to France, Belgium and Holland as well as right down to the Loire valley simply because it had more usable space than my Mondeo.
Great car but servicing can be dear.
