I disagree. I stated that you should buy a car if you can comfortably afford the monthly payment + maintenance. Beyond that threshold, it's about your overall financial goals, not just the car.
If you do not live in New York or a few other metropolitan areas in the US, a car is a necessity, not a luxury. It is a depreciating asset but it's presence in your life can provide you with more opportunities and leave you better off than if you didn't have the depreciation, but was limited to a crappy bus route.
Given that a car is a necessity, the last thing you need a car to be is unreliable. Cheap cars that have a lot of miles on them will more often than not fukk you over and have you paying a lot in maintenance fees. Should you option the car out? Life is too short to buy things just for function, and most people spend hours of their day inside their vehicle, so if you can option a car out within your means, and it makes you feel good, then why not?
Now should you finance a car or pay it off? It depends. I'd rather put as much money as I can in long term investments that average 10% per annum. So if I have a car loan with a 5% APR, I am better off financing the car than buying it outright, because my long term investments have me coming out ahead in the long run. And I would argue that for most people that can get a decent car loan rate, they are better off building an emergency fund, flooding their 401ks and Roths and investment accounts, and investing in themselves, rather than rushing to pay off a depreciating asset to save cents in interest and gain a "feel good factor".
Now if the option is between paying your car off and blowing the extra money on bullshyt, then yes, pay off your car. But if those are your two options only then you probably don't have the financial maturity to buy a car.
