So when I was employed and working like a dog I never had time to do things like sit around all day and get insurance quotes. So I just saved $774/year on my primary car insurance. The Porsche is under Hagerty's collector car insurance for $86/year.
Quotes varied quite a bit:
For six months:
California Casualty.....$837
21st Century..............$640
Mercury......................$495 - plus $120 one time broker fee
Prudential..................$452
AAA............................never called me back
This is for a single driver, clean record, with two cars - Toyota truck, and VW Jetta. The Jetta has full comp/collision/no deductible glass. I also got 100/300/100 insurance and Medical pay. This isn't a bare bones policy.
It would have never occurred to me to call Prudential for auto insurance but I called them because I have my homeowners insurance with them. Bonus - she said I'd get an additional discount on my homeowners insurance.
