Back 25 years or so I wanted a vintage 182 that would get me priority parking at OSH, Merced, Watsonville, and all those shows. Found one (literally) in a farmer's field with (literally) chickens roosting in the back seat and wings off and stored in the barn rafters. Knock in the engine. Paint total trash.
Bought it for $5k with 900 smoh on the engine, but hadn't been run for ten years. Did the old Marvel Oil in the cylinders for 24 hours (per cylinder) soak trick, had a Navy painter that wanted to make a few bucks on the side rig up a paint booth in the hangar with plastic visqueen type sheeting, fans, and all the rest of it to paint and corrosion-control the entire airframe (which by this time had been totally stripped of any and all interior/exterior stuff.
Spent the next year on seats, headliner, carpet, and every nut and bolt on the airplane removed, and either plated, chromated, or replaced.
Every Christmas Snarly Charlie gets a new toy. Be it strobes (last CHristmas), oxygen (a few years ago), GPS, and all the rest of it.
Now that was my fun. THat may not be your fun. But it was rewarding as hell, knowing that even Wichita couldn't turn out a better product. And yes, the N-number was a creation that I couldn't have gotten any other way. 2-meter rig plumbed into the audio panel for headsets with antenna in the plastic wingtips.
Forgot to say: My widow is the only person who will ever sell that airplane.
