M：Oh. Hi, there. A beauty, isn’t she? Do you want to take her for a test ride?
W：Well...Um. How old is it?
M：Well, it’s only three years old.
W：And what’s the mileage?
M：Uh, let me check. Oh, yes. 75 000 miles.
W：75 000 miles? That is quite a bit for a car that’s only three years old.
M：Well, once you’re in the driver’s seat, you’ll fall in love with her. Get in.
W：Ugh...Uh, I can’t seem to get the door open. It could be broken.
M：Ah, just give her a little tap. Now she’s opened.
W：Great. A door I have to beat up to open.
M：Hey. Get in and start her up.
W：Oh, there seems to be something wrong.
M：Well, it’s probably the battery. I know she has enough gas in her, and I had our mechanic check her out just yesterday. Try it again.
W：Okay. How much is this anyway?
M：Oh. It’s a real bargain today and tomorrow only at ＄15775, plus you get the extended warranty for an extra ＄500 for the next 30 000 miles.
W：Uh. Well, almost ＄16000 is a little out of my price range. Plus the seat covers are torn a little.
M：Well, hey, I might be able to talk the manager into lowering the price another ＄200, but that’s about all.
W：No, thanks. I think I’ll just keep looking.
