Why don't we buy a car, dear?
I have been thinking about it for a long time. I think it necessary for us to buy one. We live so far away from my company.
Yes. With a car, you wouldn't have to catch a bus to work. It can save a lot of time.
Sure, but we don't have enough money at present.
Why not borrow some from the bank? I think we won't have to borrow so much now.
Well, let's go down town and have a look.
