I have a 2011 CT200h that is due for the 90K service. What additional service should I do that is not part of the standard 90K service? Should I have them replace the EGR? Replace the transmission fluid? The previous owner had this car serviced at the dealership each time. There is a reputable Prius mechanic in my city, so I am contemplating using them instead of the dealer. Any opinions on if there is any value in continuing to go to the dealer?
