This is an awesome post,
You bought a financed car and over time you are paying the huge installments and interest you said you learned, and that you will never buy another car for financing. You noticed that you kept the money you are paying now in the car at least half of it, you would already have greater purchasing power to be able to buy one without financing in the future. So, behold, something happens, you get sick of the car, you break up, you sell, you spend the money and there is another urgent moment that you need to have the car at that time, you forget all the teaching you did for yourself and repeat the same "error".
@hranhuk that is so true...
