'If you drive a luxury car, it is almost certainly to create the envy of those (like me) who drive a cheap Honda. Or to lessen the envy you feel with respect to those who drive luxury cars.'

I drive a Honda Accord and notice that my wife's Toyota Highlander provides a much smoother ride. Luxury cars are higher in quality than cheaper cars, and one should not assume that people buy them primarily to induce envy in others.
