2010 xc60 (turbo online 6) here a few thousand miles away from 300k...

It's got a few issues, but the thing has been a beast. Not sure how Chinese it is however.

2010 was the year Volvo ownership went to Geely, so your xc60 was designed and built under Ford ownership. The xc60 is a big, expensive SUV (at least for us EU residents) so presumably there should be a quality engine in there.

Some smaller models at the time had a PSA (Ford/Peugeot) engine which don't come anywhere near 300k before blowing up (or simply becoming very expensive to maintain).

The latest electric EX30 model reuses the Chinese built Zeekr X design. Seems like they drive ok, but if they can get 300k remains to be seen. Haven't seen any used with more than around 50k on them.
