Hi Gruff,

You are correct when you say we use estar in El Imperfecto to talk about something earlier in the day, but I don't think it applies to everything. The example you are giving talking about something someone ate earlier in the day is perfect "estaba muy rico". We would also use the same phrase when you've just finished a meal (like when you put down your cuttlery on top of your plate after eating the last crumb); you would never say here "ha estado muy rico" or "estuvo muy rico". 

However I can think of other situations where this wouldn't apply. For example, if you come out of the cinema after watching an amazing film, you could say to your friend "Ha estado genial, ¿verdad?". Here we wouldn't say "Estaba genial ¿verdad?".

I am wondering if this use of Imperfecto is all to do with "food"... 

Will keep investigating... :))

Thanks Inma - that's good to know! What about the other cases where we use estar. I suppose you can use both imperfecto and perfecto for the position of the car this morning but they have a different nuance regarding whether the car is still there?

Say for example I want to say where something was this morning (my car, as you are suggesting):

"Esta mañana mi coche estaba aparcado enfrente de mi casa"

What I want to convey here with the use of estar in the imperfect is that my car was parked opposite my house this morning, without seen the action as a completed action. I may have moved the car later on, but this is not relevant. 

"Esta mañana mi coche ha estado aparcado enfrente de mi casa"

What I want to convey here with the use of the perfect tense is that my car was parked opposite my house but it generally implies that it is not there any longer. It has been parked there for some time during the morning but now it is not. It is seen as a completed action.
