These people are asking crazy money; there've always been plenty of CXs and GLs around here for $500-$750. The bikes really are the "Ford Escorts" of motorcycles between their modest performance and the fact that Honda made/sold a million of them. I honestly don't see how anyone can reasonably expect more than $1000--let alone $2K--for an average, good, or even a very good, example.
