His tag said "LESGAS". According to the calculator at Toyota, I would save $2140.32 a year. But the real question that the Toyota calculator does not answer is: How much is it worth to not drive a Prius? My calculator says about $200 – $300 a month, but that is my calculator. Also, I had to slow way down to take the picture, he may get the 55 mpg they quote on there web site by driving 60 mph on the highway. If the car cost $10,000 I might plant a tree and hug it all day but for $22,000 – $23,000 it seem high. I like diesel not two motors.
