Hertz classifies it as a YC - "Specialty Intermediate". So it is an intermediate, but Hertz often tries to charge $15 extra for it if you ask for it at the counter.

I have received them on Intermediate rentals a few times (no extra charge as they were pre-assigned to me). I love them, and have flagged it in my profile (call Hertz to have it added) as my preferred rental when doing Intermediates.
