Question

We had no car at that time. we ___ our old one

Answer 1

We had no car at that time. we sold our old one  - У нас не было автомобиля в то время. мы продали наш старый автомобиль

Answer 2

It seems that a word is missing in the sentence.

Assuming the missing word is "sold," the correct sentence would be: "We had no car at that time. We sold our old one."
