Too Many Vehicles

I am still trying to figure out why some folks they need more than one car, particularly when their own personal economy isn't all that great?

Why would you need a old car (Yeah getting rid of that one I might understand), a new car, and a truck? There is just one you so why do you need three cars...It's not like you are getting car for your child in college or your other child who isn't old enough to drive yet....

I really am trying to understand the need for multiple cars....and this kind of mindset?

Maybe some on Hubpages can help me understand...
