After the conversation, what does the woman still not know? Why does the woman ask Mr. Johnson’s home address?

M: Good morning, Mr. John’s office.
W: Good morning. May I speak to Mr. Johnson?
M: Speaking. What can I do for you?
W: Well, I noticed your want ad in the paper yesterday.
M: You mean about my Mercedes?
W: That’s right. I noticed it’s a 89 and wondered about its condition.
M: Well, it’s in great shape. I’ve been the only driver, and all maintenance has been done according to the dates specified in the service manual.
W: The ad said it has air conditioning, power brakes, power steering, automatic transmission and a convertible top.
M: That’s right. I forget to add that the tires and battery are all new, too. It has comprehensive insurance, with coverage for another six months.
W: Do you mind my asking why you’re selling the car?
M: Oh, my company is transferring me to France next month, I plan to buy a new one over there.
W: I see. But I noticed you didn’t mention any price in the ad.
M: We can negotiate that if you’d like to come see it.
W: That sounds reasonable. I’d like to see the car first. Where do you live?
M: My home address is 235 the 8th Avenue. I’ll be home all evening. Come any time alter 6:30.
W: All right. I’ll be there around 7.
M: Fine. See you then.
W: Goodbye.
