Which is the car for sale?

F: Is that the car which is for sale?
M: Yes, it’s quite big, isn’t it?
F: I’ve seen much bigger cars.
M: Well, four people can sit in it quite comfortably. And it’s very fast, too.

F: What do we need to order?
M: Well, we’ve got enough computer disks. We don’t need any more.
F: That’s right, but we need half a dozen new calculators.
M: No, we don’t. Have you forgotten? We ordered eight calculators last week and they should arrive by the end of this week.
F: I’d completely forgotten. You’re right.
M: That just leaves stationery. We need some more paper. There’s only a little left.
F: Right. I’ll order some more at once.
