I got 185,000 on my modded Mk 1 Fiesta before my sister's boyfriend totaled it. And that was a 1978 car, back when American cars were routinely traded at 24,000 miles because they were junkers by then. It was my autocross car and daily driver. Had it not been wrecked, I don't think anything would have gone wrong other than normal wear parts.
The last couple of F150's I've had have also gone almost 200,000 miles before either being totaled in a wreck or traded, and were still running fine at the time with no evidence of problems.
We've owned a Toyota and a Scion that we took 160,000 or so as well, and both are still running perfectly well for their new owners (we sold them to friends).
High mileage cars can be fine if they've been maintained well.
The Fiesta ST is due for a tuneup (plugs, belts, etc.) at 100K miles, and a timing belt at 150K. So sometimes a higher mileage car will need those done.
