My wife recently got a new job that will be a 45 mile commute each way. We had been thinking about replacing her 2000 Camry anyway, but this has had us considering it more seriously. We are interested in a used Prius, probably a 2008 (based on whats available in our area and price). One thing I had read said they are best on shorter trips. Since most of her driving will be long highway rides, should this be a concern? Thanks for any help. Sorry if its too newb of a question, I am just getting started in my research.
