Hey there I am looking to buy a bike... can you tell me about the one you have for sale...
This bike is in almost new condition, just a few minor scuffs. It is freshly serviced and an amazing deal
How old is the saddle... is there any chance you could throw in a new saddle 
If you will pay full price I would throw in a new saddle
4500 is really high for a used bike...
Not when the new ones are 6,000
I don't know , it is still awfully high. The 2018s are already out.
Make me an offer 
Well with a new saddle I could go as high as 4250, without I could go as high as 4150
I would do 4,250 with the new saddle
