Checking my math
20,000 miles/yr
Range Rover was getting 12 MPG, so 20,000/12 = 1,667 gal/yr, at $4.15/gal is $6,917/yr
Prius gets 42 MPG, so 20,000/42 = 476 gal/yr, at $4.15/gal is $1,976/yr
$6,917 - $1,976 = $4,941/yr savings
The RR really was getting excreable mileage - heavy, V8, full-time 4WD, short trips and climbing big hill daily
The Prius gets worse mileage than I'd like due to short trip/big hill, but still manages to average 42 MPG full-year
We buy gas at COST so pay "only" $4.15. If paid $4.50 would save $5,357/yr.
Kind of a best-case-scenario because Prius replaced a gas pig.

Bottomline, you are probably not saving nearly as much as you think you are...
