Hey there, I was intrested in your bike, but I have a few questions.
I still have the bike, what do you want to know?
I was wondering how long you have had it, and the condition it is in
I've only had it for 1 year and it's in excellent condition! 
That's good to hear. I am really interested, its a great price, but is there any way I could get you to come down a bit? maybe $1700?
1700 is too low for the quality of my bike! It's hardly seen any use and I've already dropped the price so much in my listing. Please reconsider.
As true as it is, I really cant go that high. could we agree upon something a little lower? maybe $2000?
2300 if you come to pick it up and I can agree let it go for that.
