I feel like I'm paying way too much for car insurance, what do you think?

29 year old male, single, live in Missouri. I drive a 2015 WRX and have been insured with Progressive for around 6 years. No tickets, only claim in the past 5 years was for windshield replacement. I did have an at-fault accident around 8 years ago but that has since fallen off my record. I also own a home and have homeowners with Progressive, so I'm receiving the multi-policy discounts on both.

I currently have 250/500/100 liability, 250/500 uninsured and underinsured, 10,000 medical, $500 deductible and rental reimbursement, and my 6 month renewal rate I just got is around $670 if paid in full, which is actually about 50 bucks higher than the last 6 months. I thought it was just Progressive being expensive, so I got quotes from some other companies and they're all in the same ballpark as Progressive.

I realize if I'm after cheap insurance, I bought the wrong car, and it's not a question of whether or not I can afford the insurance. I can. But, I guess given the clean driving record, the homeownership, the multi policy discounts, etc, I'd expect my insurance to be cheaper. Even under $600 would make me happy. I bought the car almost 2 years ago and my renewal rate has crept up slightly since then despite the fact the car's depreciating.

Does the rate I'm paying sound completely unreasonable to anyone else?
