Theres still no getting around it..Aircraft parts are way over priced. Maybe not the main aircraft structure..built in a smaller scale factory. But a huge amount of nuts bolts washers generators/alternators etc are just generic automotive stuff that is available at supercheap auto for one ten the price of the Cessna dealer. I worked for three years in GA and the owner operator of my company was constantly tearing his hair out over ridiculous prices. Especially for seals.
