You can get quotes by calling different agents, or simply punch in your basic vehicle, personal and current car insurance details into an online quote site. These sites provide you with free quotes from five or more insurers per request and you're not obliged to purchase from them. You will save a cart-load of cash if you take time to visit more than two or three quotes sites.
The two important things you have to take note as you compare those online quotes are as follows:
1. Premiums and Benefits. Make sure that the premium stated in the quotations corresponds to the benefit that you require. Human errors do occur from time to time. Although it may sometimes be difficult to get quotes for (exact) similar benefits from different companies, the coverage limits and deductibles, as well as exclusions clause and conditions should not differ much. Otherwise we'll not be evaluating these quotes fairly. This takes a little more time than the next point.
2. Ease of Claim. What good is it if you can get the cheapest auto insurance yet when you need to make any claims, the insurance company takes days to respond to your requests... And when you finally get through their hot line again, the answering machine puts you on hold for endless minutes before you can speak to an actual person who's outright rude?
Once you've identified a suitable low-cost insurer to purchase from, do yourself a favor by dialing in to their customer service hot line and their claims services hot line. Speak to their service officers and see if you're comfortable with how they treat their customers.
Before you finally sign up for any auto insurance, do a quick (final) check to see if there are discounts you qualify for and what the eligibility requirements are. After you have done your due diligence by going through the two points above, you will very likely get an auto insurance that can serve you for many months to come - regardless whether you need to make claims or not.
