The cabin air filter is easy to change also of course. My ex had a Chevy something, small car before the Cruise, that she gave to my son, with 97,000 miles on it. I knew she didn't take care of it, so I did a once over, including changing the plugs. I was afraid they were seized, but they came out easily. It drove better with the new ones, but the old ones still worked, they were just eroded and the gap was bad. I changed the wires as well, and the oil and air filter (which was pretty bad). Easy to work on that 4 banger.
I'd have the brake fluid changed maybe after six years or so. I don't do that one myself.
If you use synthetic oil, you can go 10-12K miles without changing it IMHO. Most cars now have an indicator on oil needing changing.
