I bought the car last week on 27 June and it showed up in TU and EQ, both a 9 point drop in 4 days. I am not sure if the score would stay up or down after the purchase but that is more influenced by percent utility, and the DTI for the car loan. I had a 4% utility before the purchase and nothing bad in the last two years so that is why I am thinking I had the 9 point drop only.
