Hi, that looks like the perfect bike for me. I live near the beach and ride alot.
Great! It is in excellent condition.  You will really enjoy it.
It looks silver, is that the color of it? Also are the tires in good shape?
yes it is silver and the tires are like new.
I would like to offer 170. for the bike, I could come pick it up today
How about $175 and today would be great for pickup?
Ok  that sounds great, I will see you in about an hour with the cash.
see you then
