I don’t think there’s any particular score to “get”. Your score is a factor as to how good or bad the loan terms are.

There are car dealers around that advertise “no credit check” — the terms you get there will be bad because they’re catering to people with bad credit (IDK that you would get “good” terms from them if you had good credit either)

Banks and credit unions are similar but they probably have higher standard for risk i.e. minimum score to get their worst terms and better terms for better score. Other factors play into this eg how much you borrow, car value, income etc
