One way to do this is to call the insurance company and see what the hold time is and what the service is like when you wait to speak to a representative about a general inquiry. If the hold time is 3 hours and they don’t seem like an accommodating group, you’re probably not going to want to deal with them after you just lost your house and file a claim.
Collision coverage has a deductible, which is the amount you pay before your coverage helps pay for your claim. You can typically choose the amount of your deductible when you buy coverage. So, if you choose a $1,000 deductible and your car is later damaged in a covered accident, you'd have to pay $1,000 toward repair costs. Your collision coverage would help pay the rest, up to your coverage limit.
