This is a very, very minor change or maybe it's was just bugged before.
Now you can see the "current" PP value when you go to your collection in the garage. Before it was only showing the PP from day 1 of release.
The Camaro SS had originally 553pp. After the update (which one, I can't remember) the car had it's pp down to 549, but even though the stock settings was 549, in the collection it would stay at 553.
Today, before picking the same car I checked the collection and it was still 549. Then I picked the car, went there again and the values got updated to 549.03.
Kinda useless, but there ya go.
