Hello, I'm currently a 19 years old college student with GPA below 3.0, I need to find a auto insurance company as soon as possible, I have two cars, Audi and Toyota, and I'm going to sign up the policy with my dad to get a cheaper rate. I think I'm going with single coverage instead of full coverage, it's not like that I don't like full converage, I would love to have full coverage for my Audi, but the price is just way way too expensive compare to the single coverage for me, so what's the best insurance company with the lowest price and decent/quality service? If you guys know any insurance company that offer good price for full coverage too, please let me know, I would love to have it for my car. I lived in southern California.
