Your rate sounds reasonable depending on where you're from. As mentioned before, rates can vary from one extreme to another depending on location, driving history, gender, age, credit history, vehicle information, etc.
Don't just take the first offer though; get at least 3-4 additional quotes from reputable companies online. Apples to apples quotes can be done in 2 minutes.
And speaking as a former licensed agent: make sure you understand what "minimum coverage" actually means. You don't want to be too surprised if you only have $25,000 property damage liability, and you crash into someone's $45,000 car. Liability limits can be increased to a reasonable level for (usually) just a few cents, maybe a couple dollars per month.*
