[pothole]

Personally, I don't think you can make assumptions based on mileage. You can out big miles on cars with very little wear to most parts if it's long distance motorway / highway cruising.

Meanwhile, lots of engine-battering cold starts and short journeys around poor quality urban roads can trash a car in very short shift.

I'd be wary of a high mile car. And I probably wouldn't travel a long way to view one. But if it's local and priced to sell, it's worth a look.

We all know these cars can fail. But think of it this way. Take two Boxsters, both on their original engines. One is one 100k, the other on 150k. The 150k one obviously has one of the good engines. Is it really more likely the 100k engine will reach 125k than the 150k one will reach 175k? Once you're over 100k, I'd say all bets are off.
