Hello. I have cash and am extremely interested in your bike. 
Hello would you like to know more about it. It is vintage and I am throwing in my helmet as well
I have bee researching these bikes for a long time. You are above market value by about 30%. I appreciate the offer the helmet. I currently have one. Would you be willing to negotiate the price? 
I can go down a few bucks but not to much. What are you willing to pay
How are the tires and tubes? Any cables or handles need to be replaced? Is the seat cracked? These will all affect my offer. Thanks for being willing to negotiate!
The tires are I  great shape. The seat is not cracked at all. And your welcome. I've had it for about 5 years. I bought a new one that is why I am getting rid of it
