I see you selectively went trough and made offers to a dozen or so bike owners but just cut the asking price by $200. Your range is all over from $1000 to $2000 so I don't think you have a real target bike in mind nor do you actually have money to buy a bike. Maybe you do but I'll be you don't.
I'll take your $1300 offer as long as you add an additional $200 A-Line administration fee. Not just anyone off the street can operate an A-Line.
