Saying "I would like" is entering the realm of "plausibles" or the "condizionale", in which you're saying/asking to see if something is possible/when something isn't entirely necessary. These terms are mostly precursored by the verbs volere -> vorrebe (to want -> he would like), potere -> potrebbe(to be able to -> he could), dovere -> dovrebbe (he has to -> he should).
E.g. - vorrei guidare la mia macchina = I would like to drive my car - Potrebbe vendere il pesce = he could sell the fish - Dovremmo finire il nostro compito = we should finish our homework
Correct Saxy. I passed some links about vorrei and ask the same question in this discussion
