Opinions on the M270 2.0 engine?

Hi! Ive been car shopping for a little while and I’m interested in an A250 with the M270 engine. What do you guys think about that engine? Is it reliable? Is it efficient? And what kind of mileage should I be looking at? Should I be afraid of cars with 200k+ KM? Or is it something that should be no problem?

I would love to hear your opinion and thoughts!
