I have to echo that if you're wanting a fairly common airplane, look locally first. When I first started looking 40 years ago when I lived in Laramie, I saw a Skylane at Jeffco (now Rocky Mountain Metro) near Denver which interested me--faded paint, but otherwise in good condition with acceptable avionics, at a fair price. I asked one of our local mechanics in Laramie if he'd look it over for me, but he told me about a little used Skylane right there in the community hangar at Laramie. It was in better shape, 2 years newer, always hangared, had only 350 hours on it, but hadn't been flown in over a year. Long story short, he put 3 of us together on it, and we bought it at a fair price, flew it for the next 4 years putting about 1200 hours on it. Because of the disuse, we had to overhaul it early, but it was a fine airplane--and not 2 1/2 miles from my front door.
On the other hand, if you're looking for something a bit unusual, that might require some travel. When I started looking a dozen years ago, I was interested in a 172 converted to 180hp with a CS prop. At the time, I could only find 4 or 5 anywhere in the country, using various Internet sources and Trade-a-Plane. There were a couple in Florida and one in the LA area--didn't want any that had been near salt water. I don't recall where others were, but when I found mine in Tulsa, I flew there first to look it over--always had been in dry country, which was one thing I wanted. It was being brokered, so I took it for a ride with the broker/salesman, and decided it was the one for me. I had the logs copied, they looked clean, and I spent most of a day going over it myself. As a non-mechanic, I missed a few things, but nothing dramatic--a pretty solid little airplane, low airframe hours, supposedly bullet-proof Lycoming engine with less than 1000 hours on it. A few weeks later, I bought it.
As I've mentioned here before, I only had it 15 hours before the engine threw a rod and I landed in a field. But the most meticulous prebuy wouldn't have found any engine anomalies, as a bearing spun and blocked an oil passage. Replacing the engine and doing a bunch of other upgrades while it was down made it the most expensive 180hp CS converted 172 on the planet, but it's given good service over the past 11 years. It's a great little airplane, and I expect to keep it until my flying days are over.
So nothing's guaranteed, but look close to home first. My view is find the airplane you want first, then have it examined by a knowledgeable mechanic. Airplanes are pretty personal things for most of us.
