When you talk about comparing two different cars having two different body types then you need to understand that there is no comparison between the two cars. Because every car with a specific body type is created to cater to different needs. For example, when I went to a toyota dealership in Tokyo and asked for a good off roader they suggested me to buy a SUV and I asked them for a good compact passenger car they recommended me a hatchback. So, different needs are catered by different cars with different body types. What other differences are there between a hatchback and a SUV?
