Q: Seller: Hey, you're interested in the bike?
Buyer: I am. My husband an I have been trying to get a tandem for awhile now. We sold our last one when we had kids, now that they are older, we can get back into it. How is the condition? Are you the original owner? Is it road ready? 
Seller: Yeah, this is a spare we kept in a storage unit, and we haven't been on the road in a while. It's definitely road ready.
Buyer: We know our tandem bikes and comps in the area put this one around $135. Would you take that if I picked it up? 
Seller: Oh wow you two have shopped around? Really want it then, 135 is fair. Let's do it.
