Is there a mileage limit on a second-hand car beyond which it's more likely things will go wrong?

Would you say there's a mileage limit on a second-hand car beyond which it's more likely things will go wrong? In the old days, we used to reckon that after 50,000 miles or so you'd almost certainly be in for trouble - a new alternator, starter motor maybe possibly a new battery etc. Are today's second-hand cars any different?

Anything could fail at any time. We say for most cars replace the timing belt, tensioner, water pump and aux belt every five years or 60k miles, whichever comes first. Brake pads could be anything from 20k - 80k miles. DPFs last 80k - 120k miles before filling with ash. EGRs not as long. DMFs can last 20k miles to 200k miles.
