A tricky question. After a long search I found this one quite good: A modern Spanish Grammar - A practical guide by Juan Kattán-Ibarra and C. Pountain, Routledge, ISBN 0-415-27304-8 paperback.

Do you live in California or Chicago??

[gramatica]

Does that book cover the preterite and the imperfect in depth where both are possible but the meanings are different depending of the context? Or does anyone know of a good gramamr book like that?

Thank you very much

The one I quoted touches on this, but not in huge depth. I don't know of one that does.
