I'm new to the club. Former USAF navigator (from 20 years ago) who is just starting to fly again as a student pilot. In the process of purchasing a 1971 150L model with long range tanks. Have placed a deposit. The annual is due on the aircraft. My question is: How much should a combination annual/pre-buy inspection cost? I intend to finish my private license training in the 150 and then the usual use will be for short cross country trips with my wife (about 250nm).
