I got a reply back from the seller which I didn't expect, he said he didn't mean to be snide just meant that bike prices were subjective. He wanted to let me know that he'd taken my feedback seriously, so he reposted the ad with it $80 cheaper. I still wouldn't go for it for over $350, but I appreciate that he's being more realistic with his flipping. Glad there was a happy, albeit unfruitful, ending.
