2016 320, purchased CPO at 45k and currently at 60k. Zero issues. Mostly stock at this point.

In my experience, when properly maintained… the N20 is very reliable. Knock on wood that I dont have another major accident and Ill be driving my current one til 200k miles plus.

What maintenance is important to highlight? I have a 2017 320ix with 27000miles. Ive replaced brake pads and done all the oil changes and brake pads. But what about spark plugs and other things? Any recommendations?

2. OEM Engine air filter, annual (I use a drop in which I clean/oil)
3. OEM Cabin air filter, annual
4. NGK 97506 Spark plugs every 50k miles
5. Differential/Transfer case oil every 60k miles

Tires, brakes, wipers, ignition coils, etc. as needed.

Do not rev RPM greater than 3k until temp gauge cracks off cold mark.

Use eBrake at all times when parked (engaged before selecting park).

That’s about all I can think of. Transmission oil around 60-80k miles is debatable (unless you beat on your car). Blackstone has gone on record and said it’s usually not necessary for modern/high tech transmissions, based on their data collection over the past few years. Wouldn’t hurt if the ZF procedure is followed to the letter. I wouldn’t want some retard winging it based on some tribal shop knowledge from other vehicles.
