What Affects Your Rate?
Your exact APR depends on three main factors:
- Credit score: Scores above 740 get the lowest rates.
- Loan term: Shorter terms (36-60 months) save money. Pick 48 months or less to cut interest.
- Vehicle type: New autos often get better rates than used. Most vehicles qualify.
According to Bankrate's 2026 auto financing report, St. Louis drivers save $1,800 over five years by choosing credit unions over banks (Source: Bankrate Auto Loan Analysis, 2026).
