I've been looking for a grocery bike. Craigslist had an ad for what seemed to be an appropriate choice. I got there and, sure enough, the bike was what I was looking for. I started checking it out. Lots of little things just didn't add up. Some good parts, some really bad parts, a real hodgepodge. Seller was a little too anxious and was unable to answer reasonable questions. I made a few plausible excuses and passed on the bike.
As I'm driving away, it occurred to me that the bike might well be stolen. Years of bike shop experience backed that up. I don't know for a fact the bike is hot. If it is, I don't know for a fact the seller is the thief. In hindsight, I could have gotten the serial number during my inspection.
I'm glad I didn't buy it. Should I have taken other action?
