Buyer: Hey I really want that bike but it seems a bit to pricy mind if we talk about it?
Seller: Sure, I will answer any questions you have.
Buyer: Well I get you upgraded it and its a 2017 model but how used is it?
Seller: I only used it a few times. I really do not have time to ride it due to my job.
Buyer: ok that's fine and how are the tires and current chain
Seller: Both are in excellent condition. Not a scratch on the bike.
Buyer: Ok well im working with a budget of 684. Now i should remind you this is still a used bike and even with your upgrades it wouldn't push it too 900 I could get a completely stock bike for 779
Seller: I am actually taking a loss asking the $900. I am willing to negotiate on the price, however, I cannot go that low.
Buyer: Well yes selling this. Bike without much use. Is certainly a loss for you but i did my reasearch and your exact model and your upgrades have gone down in price when bought brand new now a brand new bike with those up grades would run me about 820 so that would certainly mean your bike value has significantly reduced. If 684 is too low I can do 699 and i will pick it up
Seller: This bike was only used three times and it has been parked in a garage. It is very clean with many upgraded parts. I could do $790 and I will deliver it to you.
Buyer: How about 740 with meet me halfway delivery
Seller: I can do $750 with meeting halfway for delivery.
Buyer: 745. Sound good that's really the best I can do
Seller: Okay, you got yourself a deal.
Seller:
Buyer:
