The main difference between collision and comprehensive coverage comes down to the question of what the driver controls. Collision insurance will cover events within a motorist's control or when another vehicle collides with your car. Comprehensive coverage generally falls under "acts of God or nature," or things that are typically out of your control when driving. These can include events such as a spooked deer, a heavy hailstorm, or a carjacking.
And because you've had the nerve to spend your hard-earned money on making your modified car the envy of your manor - or at least made a start on it - you've probably heard them suppressing their sniggers as they tell you that they won't cover your modifications, and will only give you the 'market value' of the standard car if some muppet writes off your pride and joy. What a rip off!
Collision insurance is a coverage that helps pay to repair or replace your car if it's damaged in an accident with another vehicle or object, such as a fence or a tree. If you're leasing or financing your car, collision coverage is typically required by the lender. If your car is paid off, collision is an optional coverage on your car insurance policy.
