I work for my local Domino's Pizza store. It's one of the bigger stores in my area, covering a HUGE area for delivery. My boss has two Prius's as company cars that us drivers get to drive (as well as other vehicles as well). The main Prius we use has been at this store for 3 years now. It's an 04 and was bought with 90K miles on it. It is used all day long every from opening to closing of the store. It now has 186K miles after 3 years of service. There has no been one single problem with it! It is always taken to the dealership for regular maintenance when it is needed. We drivers average about 44-48 MPG when we can. During dinner rush's we can pull around 38 MPG! These things are troopers!
