Buyer: Hi, I'm interested in your bike. It's a little larger than I'm looking for, but I like the style. Would you consider accepting $150?
Seller: Hello, do you have any questions about the Bike?
Buyer: Will you sell this for $150?
Seller: No, I am willing to negotiate but that is too low. Do you have any questions about the bike? It is really in good condition.
Buyer: I think the price is a little high, I can buy a 21-speed new for $350, and that includes a warranty. What about $165?
Seller: You haven't even asked any questions about the bike. If you had you would know that it has CST 700X38C hybrid tires, Schraeder valves, Rear Shimano Altus derailleur with MegaPulleys... and many other great feaures. So, as you can see this bike has many great upgrades making it fully worth the asking price of $200..
Buyer: I'm familiar with this model of bike, my brother had one just like it. You didn't mention those upgrades in your listing though, that does add a little value to it. I'm still not sure that it's worth quite $200 though considering what I can buy new for a similar price. I'd be willing to raise my offer to $150.
Seller: That is why I kept asking if you had any questions. I'm a bit concerned you're just a reseller looking to undercut other buyers and then make a profit. If you want a new bike without all these great upgrades you should definitely get one. But all things considered I think I'd better not accept such low offers right now. I can go $195.
