How to find out when my car requires maintenance?

I bought a new Honda and when I read the owner's manual it just says to rely on the maintenance computer to tell me. But I want to know in advance what miles I will need Tune-up, new spark plugs, fluid changes etc. But none of this is covered in the owner's manual!

So how do I find out about what mileage I will need to perform these services?

1974 celica gt vs 1990 mustang 5.0?

Having a thought time to choose which car I want to purchase. The celica is in good condition besides it needing a timing chain but they want to trade for my daily driver older Honda. It still runs and looks great. The mustang looks like it needs work all around, it's an auto, and needs a fuel pump and more for it to run right. For 1200. The mustang is a blind buy because I never heard it run for over 2 secs. I'm trying to figure out should I trade my car for the celica or just outright buy the mustang. What you would do value wise, mechanic wise and uniqueness wise.

Can a Honda dealership get phone recordings?

I recently got a starter repaired at Honda. But over the phone my advisor said they are replacing the switch not the starter. Clearly he lied to me over the phone and now I'm stuck spending 500 on the starter and who knows what in the switch. I'm calling corporate Monday. But can they retrieve calls with my advisor?

Car keeps dying when driving?

I have a 1997 Honda Prelude. After a few blocks of driving the car suddenly loses power and dies and the rpm drops. It happens after a few blocks of driving or when I launch and downshift. I check oil, it's fine. No check engine light, the last time it was a knock sensor and I replaced it and light went away. But it still drives horrible. It seems stuck or something. I took it to a mechanic and he couldn't find the problem. I'm stuck on this for weeks now
