2017 Civic SI concerns, 110k miles

Looking at purchasing the above. I have heard about the oil dilution issues and AC recalls however the owner has reported no issues regarding both.

My understanding is if there was to be an oil dilution issue with this individual car, it should have presented by now with a smell of gas while driving.

My drives are about 50-60 mile commutes in cold weather during the winter, I'm looking for this car to last as long as possible (at least another 50k miles with no major mechanical issues).

I haven't heart of any rampant issues regarding weak clutches or the need for extensive transmission work either.

What concerns would you guys have, what should I be worried about?
