How does car insurance work? (also whats better buying a car vs leasing)? - cheapest car leasing

including the 16 now. Planning to save up to 18 years to buy a car. My first question is, how can the car insurance? I know you have to pay monthly based on each vehicle to another, but the cheapest car insurance when renting a car? or if you bought it?

I also know that each vehicle depreciated much more each year. At first I thought about renting, but now Im not sure. can someone tell me what would be a better option long term?
