Having someone inspect it is a good idea if you trust that inspector. About ten years ago a local friend who knew nothing about A's found a pickup in the LA area that sounded good. I knew a former LA MAFCA board member! and asked him to recommend someone he knew down there to inspect the car. He did, and sent his acquaintance out to look at it. He came back with a positive report and my local friend sent the seller the money, hitched up a trailer, drove 1000 miles to get the car.
It looked good, but in the event it wouldn't start, and had two flat tires. The roof was installed incorrectly, as was the header. If I had been able to go with him, I would have told him to forget it. But he bought it anyway. When he got it home, we discovered it had two sticky valves and wasn't timed right. It took us about 12 hours to get it diagnosed and repaired and running, and fix the flats. He loved that truck after that, and eventually sold it to his neighbor, who also loved it, and bought a better one.
I doubt the "inspector" ever even looked at the first car. The moral of the story is, get an inspector you trust and who really knows what they're looking at!
