Not my cup-o-tea but no doubt it is a top notch build. Maybe trying to be the next Jesse James and using the bagger platform? Brave soul putting his phone number on an ebay ad IMO.
As the seller points out in his ad, it most definitely is a trend. It reminds me of the Bourget/American Iron/Big Bear style choppers that RUBs were paying $50K for 5-10 years ago, and you can now see on Craigslist for a fraction of that. Don't get me wrong, I love the look and think baggers are long overdue for customization, but if you chose to put $50K into your bike, don't expect to find many folks willing to buy it from you for that.
