They have sure depreciated.
Makes perfect sense. It's an ugly, useless little car with batteries that are exceptionally expensive and have a lifespan of only about 100k miles.
The Prius makes no practical sense. My Civic averages approximately 30 mpg (hand calculated) with a 70/30 highway/city split. It has 80000 miles. Let's say a Prius gets 60 mpg doing exactly the same route (note: EPA estimate for the Prius is 51 mpg at best). That means over 80000 miles at an average cost of $2. 50/gallon, the Prius saves me $3334.
A Civic coupe EX is $19455 (that's the one I have).
A Civic bare-bones base model is $15455
A Prius bare-bones base model is $22400.
The difference between my Civic coupe EX and the Prius is $2945. Between the base Civic and the Prius it's $6945.
Even being conservative toward the Prius (60 mpg - good luck), it makes no sense in terms of fuel savings.
Had I bought a Prius rather than my Civic EX, I'd theoretically be ahead by $389. But I suspect if you factor in maintenance on the Prius versus that on the Civic, the balance is easily tipped in favor of the Civic.
This is why I roll my eyes at Prius owners. I think, "did you bother to run any calculations before you signed the check?"
The Prius has only one purpose - to give the owner a smug sense of self-righteousness.
