Hybrids - cost of ownership

Just going to post up about this. My dad got a prius to replace the forester XT he gave me. He commutes into the city and gets in the high 40’s in the winter and mid 50’s the rest of the year. In the XT in the same driving got around 18-21 mpg on premium as a comparison. In highway driving however the mileage goes down to the mid to high 40’s. It cost about the same as any of the other cars we were considering and has the keyless start/entry system which the other cars we were looking at didn’t. The torque from the electric motor saves it from being completely gutless to drive, traction control system kills any fun around corners however.
