Used 2010 Prius IV

Hi all, I am new in the forum. I would like to know if this is a good deal is a 2010 Prius IV with solar roof package, remote engine start package, navigation, leather seats, and all the stuff that is included in the IV trim. The car has 28K miles. I test drove the car and it is in great condition both interior and exterior. Obviously is an 2010 so it has minimal scratches. The price is $24,450 plus taxes and a $149 dealer fee. Is a CarMax dealer, so that is their final price "no haggle price". What do you guys think? Thanks for your responses.
