Redundancy is one of the causes. You use Car B to go get parts for Car A while it is being dismantled at the garage. Another example is the usage of many cars for varied purposes. When I need to move more people or items, or when the weather isn’t conducive to cycling, I have a motorcycle and a sedan. Another reason is that some people dislike being followed home by automobiles. In some ways, he reminds me of a dog. You see it, pet it, and soon after, you acquire another dog. Cars have a similar sensation. I bought my first automobile in 2003, and by the end of 2010, I owned three. My father had a thing for Ford automobiles, and at any one moment he had four or five of them.
Having multiple low-cost vehicles is more cost effective than having a single high-priced vehicle. You don’t have high-cost collision insurance on any of them since they aren’t worth the money.
At one time in my life, I had up to five vehicles.
Only money stands between me and a couple of dozen vehicles and trucks. I’m not a huge fan of supercars, but if I had the money, I’d probably buy one just for fun. Modified automobiles are more personal to me since they are truly mine. Any filthy rich person can go buy a supercar but not many can build one.
