Hello, I am very interested in buying your bike.
Great! It is a perfect bike!
Are there any parts of the bikes that are still broken?
No parts that are broken, I fixed it all up. it may need some TLC with the shifter in the next year or so. Other than that, it is in sound, working condition. 
That's great, how old is it?
I have owned it for year. The owner before me bought it brand new. It is twenty years old. 
Ok this all sounds fine, but do you think you could come down to about $45?
I really cannot. I put original handlebars on it and new fenders, each easily cost more than $45 each. I could go down to $65, but that is about it. It is a great piece and needs a home to be used in!
