Looking at a 2013 335is e93 after selling my 2011 335i e93 (non M sport)

I’ve found some with mileage around 80k, but good service records.

What’s the maintenance like on in the N54 once the mileage gets up there? I bought my N55 at 76k and sold it at 130k. I took care of the engine and it still seemed quick when I sold it. It was on the verge of needing a new valvetronic servo motor, tho. I kept it stock. Spent about $13k in maintenance in the 4.5 years I owned it.

I don’t really redline my cars, and I’d probably do some light mods. What will maintenance be like on an N54 that isn’t raced compared to the N55?

I’m also looking at a 335i Msport just in case the N54 is not a good idea.

Thoughts?
