What can we learn about the woman’s car?

M: It seems that you have hardly got anything on your tray.
W: Yeah. I guess I’m just not that hungry.
M: What’s the matter? Aren’t you feeling well?
W: Well, I’ve been really worried. It’s my car. [4A] It’s in the shop again.
M: Really? What’s wrong this time?
W: I don’t know exactly. Something’s wrong with the brakes, I think. It’s really a big trouble to have such a car. [4A] I have to pay for the maintenance every time it breaks down.
M: Well, [5A]at least that shouldn’t cost you much to fix. Parts are cheaper for all the American cars like yours. Did the mechanic say how much it would cost?
W: He said he would call me with an estimate later on today, but he hasn’t called yet. And I am really anxious to know that.
M: Watch out he doesn’t try to take advantage of you.
W: What do you mean?
M: Well, some car mechanics, if they think that someone doesn’t know much about cars, they might try to overcharge that person.
W: Maybe so. These things always happen nowadays. [6D] But I trust this guy. He was recommended by one of my neighbors. He has done some work for me in the past and his prices seemed to be reasonable.
M: Oh, that’s good to know. Maybe I’ll try using him in the future. By the way, [7C]do you need a ride home after class today?
W: Oh, I’d sure appreciate it. It’s really tough getting around without a car when you live off campus.
