Why not? Buy a brand new hybrid and use it for more than 10 years, instead of buying a 10 years old used car and use it for two three years until its mechanical parts are so used that it fails constantly. Of course the best for the environment is to buy a bike(you only need to manufacture 10 kilograms instead of +1000), or just walk, if you are going to buy a car anyway buying a Prius helps to develop electric cars, witch is better at least for cities environment(less diesel particles in the air, asthma, cancer and allergies). It is way easier to control energy plant combustion particles than in individual cars, and on some places in the world you could use local wind solar , geothermal, biomass(wood, stubble) or nuclear energy along with gas or coal.
