If you want cheap car insurance, here's some tips:
1. Don't get tickets
2. Don't buy any sports car (2 doors, 4x4 trucks, etc all count as sport cars).
3. Don't live inside city limits, almost any "major" city (even Akron size cities).
4. Don't be a young (16-25) year old male.
My oldest son's insurance, when he got his first truck at 17 (4x4) was $300/month for just adding him. My wife and I's insurance combined for 2 people and 2 cars before that was $200/month (full covered). So we went from $200/mo to $500/month overnight.
He eventually moves out and my 2nd son, 18 at the time, gets his license for the first time and just to add him to our 2 cars...we went from $200 back to $500 again.
My middle son (now 20) has had 10 points on his license since then (couple speeding couple accidents), and our insurance kicked him off ours (he lives at home and I had to sign something that said he was not allowed to drive my 2 cars or they would not be covered), he has his own car now, and his insurance on his own, through progressive, is $500/month (full coverage, he has his own car with a payment). That is not a typo.
My wife and I are back to about $250/month now (just costs have gone up in 5 years) for 2 full coverage cars.
