Re-stated what the anon says:

If the bonus "Series" isn't unlocked due to regular series progression hasn't unlocked it, then some cars offered for a discount "May" be available for a GiN price- which would unlock all the bonus series that car is used in.

With that said, it's rarely to the player's advantage to buy a car under those pretenses (for a variety of reasons). Mostly because once you start playing an advanced bonus series before you reach that state, you quickly make very expensive cars become available for their showcase discounts, which Could deplete your series progression resources quickly.
