Financing a car tips?

Hi all!, my first post on this subreddit.

I am thinking of getting the mirage just before my semester starts. My situation is I just graduated from my local community college, and need a car to commute to the college I'm transferring to for my 4 year, will be under my parent's insurance, tuition’s taken care already so I dont need to worry. Did some hefty research of the mirage, don't mind about the flaws, as long as I get from point A to point B, all I care about, and fuel efficiency as well. So far, I'm planning to finance a 2024 base ES model, put a 5-6k down payment on it, 60 months. What do you guys think? I kinda am thinking to get a used one as well if I can find a good deal (low mileage specifically). Lastly, I am not sure if the dealers also partner with like other credit unions like capital one, etc... (Apologies, this is my first time getting a car, and been scouring on the internet on what I need to do before buying one, and getting the best deals). Thanks everyone and cheers :D
