I spent $25,000 for my plane and also figured I wouldn"t have to put a lot into it. It too was just overhauled. A suggestion made to me was to let the plane get more hours on the new overhaul because if something shows up, it should show up in the first 50 hours or so. (However, with this low hours, one can break it in as he wants it to be broken in.) However, if 50 hours were put on my plane before I purchased it, I could have saved the money in correcting corrosion in the fuel tanks and having the bolts pull out of the lower case. Someone said that with your first annual on the plane you buy, expect to spend more money than just the annual fee. I believe this is really true, even if you have a recently restored-overhauled plane. I believe now the "kinks" should be out of my plane and I should have many years where the major cost will only be the annual---$250 owner assisted in this area. (But I won't be holding my breath and I don't plan to quit my second job that supports my flying addiction).
