I never asked about a oil analysis, from my understanding oil was changes during the annuals, it has always been hangered, he's asking $45,000 for the bird, I haven't haggled at the moment because I want to see how the pre buy goes before I make any kind of offer. I talked to my A&P friend that I have made over the years and he wants to pretty much do an annual on the plane, testing the mags, compressions, airframe and landing gear. He told me that they'res a test that he done that required using a magnet to test the airframe for corrosion. But anyways I want my first plane to be a enjoyable experience not a nightmare
