Actually yes, but it takes a lot of patience and luck. Patience because most bikes listed are junk, luck because if a good one comes up there are people who watch Craigslist constantly and as soon as a good one comes up they snatch it to resell on E-Bay, and then more luck is needed to get your size. But over the last 7 years I've found a 86 Nishiki Olympic, ridden a fair amount in average condition; 85 Schwinn Le Tour Luxe in brand new condition ridden about 250 miles; an 84 Fuji Club ridden about 5 miles but in excellent condition, not new because it suffered from minor scratches being stored. They were in my size too. So it took 7 years of searching and luck to find those, I don't scour the pages every 5 minutes, maybe once or sometimes twice a day. I don't buy to resell either, so if it's a nice bike and if it's too big or too small I just pass, I don't have the time to hassle with reselling. I have never found anything in a Goodwill type of store or garage sales though, all junk bikes. But I live in area (Fort Wayne, In.) where cycling is not a big deal so finding good used bikes is difficult. I did find a great bike at a garage sale once in Santa Barbara Calif about 15 years ago, a 88 Miyata 712 in nearly mint condition and I wasn't even looking for used bikes back then, just saw it driving by and stopped. I bought a 87 Team new so knew the quality of Miyata's were very good then I saw it was a 712 and it fit so I grabbed it for $80. I wouldn't recommend an LBS because they will over charge for vintage bike, unless it's a bike you've been searching for and are tired of searching, and just have to own it, and don't mind laying out the cash to get it now.
