Basically, collision coverage covers damages after your car crashes into something - such as a car or stationary object. Comprehensive (also known as OTC) coverage is everything else: Mother Nature, and acts of God, to thefts and vandalism (more info). Comprehensive and collision get bundled together, and pay for repairs or replacements up to the car’s current cash value (car's market value - salvage value).
The best car insurance companies have a few things in common: They have straightforward shopping experiences, take good care of policyholders after a crash and treat their customers with respect and courtesy. That means only insurers with high customer satisfaction scores and relatively few complaints to insurance commissioners make it to the top of our list of the best auto insurance companies.
