Just hit 80,000 miles on my 2004 Prius!
Actually looks like the odometer has a little burn-in, the "7" part of the first digit is brighter than the rest of the "8". Prolly will normalize after some use.
A little math...
80,000 miles at an average of, let's say 46 MPG (it tends to be around that), that works out to about 1,739 gallons of gas. Damn, that's a lot of gas! Not sure what the average price of gas has been over the past few years, let's say $2, that works out to about $3,478 in gas.
If I'd had a lower MPG car, let's say 25 MPG, the gas would have been $6,400.
So the Prius' higher MPG has been a savings of $2,922 so far.
Plus the emissions are lower on the Prius, so there's that, too.
