I am not sure I agree with the emergency fund barrier to buying a car. It’s neither here nor there. If you are saving to cover expenses based on your needs that is good. Emergency funds are in many ways unrealistic and as unrealistic as telling retirees do not keep your money in stock. Situations are not one size fits all. If you have a stable job in a stable industry and are healthy your emergency fund needs are not as great. If you had a medical catastrophe your emergency fund is a pittance regardless of whether it is a six month fund or six year fund.If the answer to 1 is no, then you shouldn’t be buying a new car, and you certainly shouldn’t be financing it!
If it’s an emergency and you absolutely need a car because you have no alternative transportation options (bus, friends, family) AND such transportation is necessary to earn an income, then you should be purchasing the cheapest car you can afford in cash (a beater).
if you don’t have an emergency fund in place, you’ve got no business buying a car, and getting a loan on top of that is recipe for financial disaster. Just digging a bigger hole.
The vast majority of people will finance a car.
