What issues to look for above 90k miles on a 2018 330e

A 2018 330e has appeared locally for a reasonable price, mostly because of the mileage which is around 88k miles. I'm wondering what possible issues, or service requirements that I need to ask about.

I'm guessing based on the approaching 90k, that I need to see that it's had an inspection 2 and a second inspection 1 done before accepting as it's nearly at the point of repeating the inspection 1.

The other thing that comes to mind is oil changes and condition of the petrol engine. As this car has done ~29k miles a year, I'd suspect a lot of petrol engine driving and relatively little electric motor driving. But the main concern is that if they didn't change the oil every 15k and left it to every 12 months?
Is there something to ask more closely about in the event the car has gone significantly >20k between oil changes, or have things moved on every further that as long as it's every 12 months exceeding 15k is fine? Or should this car be already on high mileage oil?

What about battery life? I'm reading 3-5 years for battery's, though also seeing 6 year/60k miles quoted as the battery warranty? though for this given the higher mileage, likely longer road trips presumably it's closer to 5 years. Presumably this is something I would be having to look at replacing them in any 2017-2018 cars anyway (looks like ~€8k for the 5 battery modules).
