The price for P35328 was $74,300, is now $73,200. (I assume that's what you're talking about since that's the only 60 CPO in Canada currently).
Note also that all cars except one are shown as having been added on the 13th at 10:30. So, for whatever reason, all the cars disappeared, then were added back all at once. All but 4 have had price changes at some point.
