I think that at the moment, the credit crunch mostly applies to banks and other businesses. Maybe also to people applying for new loans. But as far as people who already own their stuff, I think it's the unemployment numbers, layoffs, and other job-related issues that are making it difficult for a lot of folks to make ends meet, so there may be more people selling off their toys. There do seem to be more than the usual number of listings of bikes on Craigslist, but who knows?
I AM glad that I had the money saved up for my trike--don't think I'd want to take a loan for it these days.
