He collects some cars that are antique.
I know the relative pronoun “that” is the subject of “are” here.
This is the letter (that) my mother sent me.
I know the relative pronoun “that” is the object of “sent” here.
But I'm not sure of this one:
I don't remember the year (that / when / in which) I bought my first car.
We can have the relative pronouns "that" and "which" here and also the relative adverb "when".
"That", "when" and "in which" (or just "which" ? ), they all act here as adverbials (adjuncts if more precise) of the relative clause "I bought my first car".
Also I'm not sure of this one:
I don't remember the year (of when) I bought my first car.

Am I right and if not, then why?
Thanks!
