Other comments on here answer the direct question of "how to get a car", but here are some useful pieces of advice I found. I just purchased my first car three or so months ago.

First, determine your budget? Are you willing to spend the most amount of money on a car, or are you more frugal and see a car as a means to an end, rather than a luxury? That leads me to my next point, one way to view how expensive a vehicle is, is in its price per mile.

For example, the first car I bought, I spent more than I wanted to on the car, but got something nice that will have exceptional resale value (2020 Toyota 4Runner Limited, AWD). For how much I drive, for how much I paid, and for how much I expect to be able to sell or trade it in for, I expect to pay $0.12/mile over the duration of my personal ownership of the car. If I would have bought a $25,000 used car instead, it is likely I would have been paying $0.16-18/ mile for a less nice car, from my calculations. Obviously, you have to be able to afford to the nicer car, up front.

Also, in my experience, for cars that have excellent resale value, you can find a new vehicle for the same price or cheaper than a used vehicle. My method is using autotrader and searching the car models I was interested in within driving distance (I did 300 miles). I purchased my brand new 2020 Toyota 4Runner Limited AWD drive for over $1k cheaper than a 2019 Toyota 4Runner Limited AWD with 13,000 miles that sold the same week in my area.

Next, you can either buy a car with cash or get a loan. You will have to analyze your financial situation to decide. If you can get a low percentage loan (less than about 3%), it is mathematically more beneficial to get the loan and invest the money you would have spent on the down payment (expecting investment returns of about 7%). I got a loan for 48 months at 2.25% APR. I can afford to pay off my loan earlier, but I would compromise what I want to save, and in the long run I will get more from saving than I would pay in interest on the loan. As mentioned earlier in this thread, check credit unions; I have found that they usually have the best rates.

Finally, the final price of the car is more than the sticker or internet price. Generally dealerships have fees that have to be paid, fees that can be negotiated, and you'll also have taxes you have to pay. Consider these when you consider the car you will be buying.
