I see lot of people try to make a sense about what car to drive and to criticize other people's choice, check out this one:
http://en.wikipedia.org/wiki/Maslow%27s_hierarchy_of_needs
To some people, driving a good car is a way of showing self-esteem, i.e. self-worth. No need to make to fuss about it.
Steve Jobs was on top of the hierarchy of needs. His way of showing his worth is by changing the way of other people's life, which is at the level of "self-actualization". Unfortunately, most of us can't reach that high. Wherever we are, as long as we feel good and not to stretch ourselves too far.
