The car had still cost Jake 1500 even after the price was reduced.
I am currently learning past perfect and I don't understand why the above sentence (which has no particular context) uses it.
From what I understood, you use past perfect to describe the idea that something occurred before another action in the past.
The price was reduced first, then Jake bought the car, right? Does that violate the rule of past perfect?
Are there more uses to past perfect that are not listed in my book?
