Kia K5 EX fair price

Hey y’all! I live in Missouri and I’m looking to buy a 2025 Kia K5 EX. I’m willing to buy out of state. What should be a fair price and APR I should be going for? I have a 700 credit score and I saw a dealership with 3 of the same Kia K5s like the same interior and exterior color. They are discounted around $5000 which is pretty decent but still I’m looking for a best price possible and I would really appreciate some help and guidance with that. Thank you!
