Everyone buying a Prius should know that the car has not got a resale value and should not blame the car but themselves. All the "resale" mentality people should buy Rollas (xli,gli). They dont deserve the luxuries of a much more better car.
And for you "savings" issue. If we only look at the "fuel cost" perspective. here is a simple illustration of savings that a Prius owner can generate over a period of 2 years.
Km travelled 50,000 50,000
Mileage 22 kml 10 kml
No of years 2 2
Petrol Price 84 84
Litres Required 2,273 5,000
total cost 190,909 420,000
So even if i sell my prius after 2 years at a 2 lac rupee loss, i will be highly satisfied.
Nd remember, the more u travel, more the savings..
