First don't assume that just because some companies claim they are going to be the cheapest, doesn't mean that always is the case. Some companies will boast how much they have been able to save certain insureds and that they dominate the market with their rates, it's always a good idea to shop even the companies that appear or supposedly aren't cheap to get the real picture.
Something also to consider is your address and credit score. If one driver's address shows up as your old address and yours is the current address your company may get what's called a no hit which can decrease your discounts, while still being able to provide coverage. It's a minor thing but important if you're looking to save. Also be aware that your credit does play a factor in your car insurance. If you have a high credit score you're more likely to have a lower rate when purchasing your car insurance.
Youre car does play a factor in the rate in which you're purchasing. If you're buying a mercedes SLK 2019 your rates are going to be much different than if your insuring a 2000 ford focus. It's just logic. A mercedes not only requires collision and comp deductibles but it also is just a more expesive and potentially high risk vehicle
Most of this suff is in the video. Keep an eye out for these things and you'll see your rates go lower and lower.
