Please take a glance at the quotation from BBCLEARNINGENGLISH.COM
Code:would or used to? When we are telling a story and recollecting an event from long ago, we often prefer to use would to describe repeated behaviour in the past, although both would and used to are possible:
Note, Ehtisham, that would in this sense describes past events and actions. It cannot be used to refer to past states. To describe past states we can only use used to:
- Do you remember what we used to get up to when we were teenagers? How I would wait for you nearly every afternoon after school and then we would stroll home together across the park, holding hands, and you would feed the ducks on the pond while I had a cigarette?
- I used to live in that house over there. (NOT: I would live in that house over there.)
- I used to own a 1966 Silver Cloud Rolls Royce. (NOT I would own a 1966 Silver Cloud Rolls Royce.)
- I used sometimes to drive to work in it.
- I would sometimes drive to work in it.
