Disagree
Completely disagree. I have owned 2 airplanes (a Grumman Yankee, and a Seneca) and neither was ridiculously expensive. I'm not sure who you're paying $100-150 labor to change your oil, but that's not the going rate. I used to buy oil by the case and do it myself in about 30 minues. Never had a vacuum pump go out on me in either of my planes or anything I've ever rented. In 6 yrs of owning my Yankee I overhauled the AI (<$400), fixed the radio, repaired the muffler and tail tie down, put in a new carb heat cable, and put new seals in the fuel tanks (a week before I sold it). I also painted it and put in new canopy glass just to make me happy. I counted up every penny I spent on the airplane (not including the price I paid, because I sold it for almost double what I bought it for) and divided that by 500 hrs of flight time, my total came to $21 an hour. If that's what you call ridiculously expensive, then okay.
Totally agree! My advice is to make sure the pannel has in it what you want when you buy it. Avionics depreciate faster than any other component of a plane.
