I am just wondering about the usage of the Konjunktiv II form vs the würde-form with sollen and wollen, and also with weak verbs in als ob clauses.
I have heard that the modal auxiliaries are generally used with the simple Konjunktiv II form, but with sollen and wollen their simple Konjunktiv II forms are the same as with the indicative preterite. So would they still generally be used with the Konjunktiv II form?
Wenn ich ihm das Auto zeigte, würde er es wollen/wollte er es
[If I showed him the car, he would want it]
Wenn er das Auto wollen würde/wollte, würde ich es ihm geben
[If he wanted the car, I would give it to him]
Wenn er älter wäre, würde er einen Beruf finden sollen/sollte er einen Beruf finden
[If he was older, I don't even know how I would say that last bit in English. Sorry if that does not sound natural but I could not think of a better example with sollen.
So could somebody please tell me which option would generally be taken in written and in spoken standard German? I really am not sure which one would be used, because the würde form would be clearer, but I have not read about any exemptions to the rule of thumb that modals use the simple form
Also with this sentence:
Er sah aus, als ob er weinte/als ob er weinen würde
[He looked like he was crying]
Which form would be used in spoken and written German? My assumption would be the würde form in spoken German because it is a weak verb and the simple form (weinte) in written German because the subjunctive nature of the sentence is already clear because 'als ob' clauses are generally in the subjunctive.
