I don't regret my GA airplane ownership. It's been central to my personal and professional life for the last 9 years. Wouldn't have married my new wife without the travel utility it afforded me then; it'll continue to serve me as a commuter vehicle when I get back to TR status and transition to the airline life. I've flown the family around countless times; the memories I've made with the kiddo already are priceless. I foresee to transition into aerobatic-capable cruisers once the traveling mission ratchets down to a 2-seater for me and the weef.
I could have a much bigger savings account if I had banked the monies I've spent in GA for the last 6 years but I have zero regrets. I wouldn't give the experiences back for anything.
