That is correct buying a car could either be a good investment or not. If you own a business or you use cars to go from one place to another for business purposes it could be a good investment. But buying one just to show-off and for fun or collection is not a wise move. My business professor at university used to tell us if you want to invest in cars make sure that you are buying one for business purposes, there are a lot of expenses in owning a car such as maintenance, gas, toll fees, etc. and if you are not using it to earn, the don't buy it.
Unfortunately the rental car services suddenly made even buying a car for business not really a smart move. After all you check having just one car and using that and you check rentals and check that and costs would be getting closer.
Now if you are a regular person who goes to work and comes home, like a 9-5 worker, you should try to find a way to use public transportation (well not in covid period lol) because that would be a lot cheaper, but let's assume that you bought a car so you can go to work and come home, and you could go around, basically just to make your life easier, sure that is not a good "investment" but also buying a ps5 is not an investment, buying netflix subscription is not investment, some things in life are not investment.
Yet if you are a business, and for your sales people and technical service on spot people etc etc, you need about 10 cars? Instead of buying them, renting them could be cheaper, between all the costs of cars, having 10 cars would be too much capital stuck with cars, while still paying a lot constantly to keep them running, whereas renting is none of that.
