Your interest rate (APR) depends on several factors: your credit score, loan term, down payment, the vehicle's age and price, and current market rates. A stronger credit profile, larger down payment, and shorter loan term typically earn lower rates. Rates also vary by lender-which is why Castle Kia McHenry works with multiple sources to find you the best option. Yes, you can discuss rate with our Finance team, especially if you have options or have improved your credit since applying. **Get your rate.** Call **(815) 453-8566** to discuss what rate you qualify for and how it's calculated.
