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 .
