I am old enough to go out of station with/in/on my school trip.

  • Here I am confused about ''with'' ''in'' ''on''

My car or motor bike is 34 years old /I bought my car or motor bike 34 years ago so it's very old.
I am too old to drive a car.(I can't drive a car easily because I am still a child)
I am old enough to drive a car.(I can drive a car easily)

  • Here is the ''old'' used correctly?
