That does seem like a lot for just 6 months for a Sonata. Are you single? What is your detuctible for collision and comprehensive? What are your limits for liability, bodily injury, and property damage. I know these questions can seem invasive and feel free to not answer them, but they would help to determine if what you are paying is reasonable or not. I would suggest you get quotes from several other insurance companies. When I shopped around 25+ years ago for insurance for my Saab, being under 30 at the time, I surprisingly found State Farm to be the lowest among the major insurance carriers back then. Since then I have been more than fairly treated by them through thick and thin and their customer service has been more than satisfactory.
Living in Colorado for that last 25+ years, both single and married, I've never paid more than $1200/year for car insurance. I now have 250K/Liability, 500K/Bodily Injury, 250K/Property Damage with a 250 deductible.
