Watch Dogs 2: Season Pass or DLCs?

I'm keen to get the WD2 Season Pass on sale, but I've got a question. Is it better to get the Pass or buy the DLCs separately?

I know the Pass, except for three main DLCs, gives you the Zodiac Killer mission, two cars, psychedelic pack and a pistol, but buying the main DLCs separately costs two times less than the Pass.

So, is the extra content worth paying for? (I'll be playing single player only.)
