If you have the funds for a car get it. The problem is peoples idea of a car. A car is necessary if can afford it as an adult. It can help you save time getting from one place to another and also make your life easier. What are you making money for if you can’t at least make your stress simple. You don’t need to own a luxury car just one that is neat and comfortable.
If you don’t have the money to get a car or a house then I understand you but if you can comfortably get one but see it as a bad move you need to have a rethink.
I understand your point, people feel that if they want to buy a car it must be expensive ones and I believe that these person's that think this way are those that have competitive mindset in things that don't really matter much, I think i support what you said, what matters about buying a car is affordability and maintenance, once you know that you can afford to get a car for yourself and still maintain it without encountering any stress or having to rely on the money you use for the most needful to keep it up and running, then you are good to go on that but if you can't thats when car becomes a big liability although ordinarily we know that car is a liability but it becomes an obvious liability when you know you don't have what it takes to maintain it then you went ahead to empty your savings to buy it, I think that will be attributed to a financial mistake.
