Lucy , what are your priorities when buying a car ?   I guess the first thing is the price , the second is the size , and of course the color will play a role too . But I have to be honest . It is our today ’ s responsibility to take care about our environment . Therefore , I will also pay attention to the fuel consumption of the car . You know , the rise in gasoline prices is huge . So I would rather to consider a smaller car with smaller engine . For which I can also save some tax . Last of the list , I also consider the safety .   What about the environmental factors ?   Well , I do prefer the lower emission cars as long as it doesn ’ t cost much . Some environmentally-friendly cars are really expensive .
