It's been exactly three weeks since the last time that I found something on CL that I didn't need and wasn't looking for but was interesting enough at a good enough price that I bought it anyway.
The biggest problem with CL around here is that there are so many bikes listed (about 3000 at any given time) that you need some luck to filter through and find a bargain -- luck because if it's easy to find someone else will have probably found it before you. Selling is also less than ideal -- as Insidious C. said, hit or miss -- but so far I've been able to find buyers whenever I was patient and willing to be flexible with my asking price. A lot of overpriced bikes that get re-posted over and over.
