My cost of flying a 150 for 13 years is around $4000+ a year for around 55 hours of flying time.
Be aware this can vary year to year with good years and other years not as good. That is why I work extra jobs, it is worth it to me. My wife goes along with my ownership, and she has the cost of the plane and flying down to the penny. IF one is considering ownership, the costs need to be considered.
