I replaced the power steering pressure hose in my wife's 2007 CR-V yesterday, saving hundreds of dollars in labor and parts upcharges from a garage... best guess is at least $500 saved, based on how long it took me, the typical shop rate (approaching $100/hr nowadays, even for non-luxury brand shops), and list price on the part. IMO one of the most mustachian skills you can learn is how to repair your car (assuming you need one), simply due to the ridiculous labor rates that garages charge. It does require some investment in tools, but honestly most of my repair work is done with basic wrenches, ratchet/sockets, and screwdrivers.
