To help you figure out if you should purchase collision coverage, you should estimate the approximate value of your vehicle. While there are a number of online resources that can help with this, including Kelley Blue Book, we recommend you speak with a State Farm® agent. In addition to helping you determine the value of your vehicle, our agents can tell you how much extra you'd pay to add collision coverage.
Let's use the aftermath of Superstorm Sandy as an example to illustrate the differences between collision and comprehensive. Within that storm, let's consider two events that might have happened: 1) a heavy tree branch fell on your car, or 2) you swerved to avoid a falling tree branch and wound up crashing into a tree. In the first event, you had no control over when or why a tree branch would fall on your car. This kind of accident would get reimbursed under your comprehensive policy. In the second situation, you were driving the car and ultimately swerved into the tree, which makes it a collision, and collision insurance therefore pays for the damages. Events like the hypothetical ones stated above are why it's important to differentiate between the two types of coverage.
This coverage reimburses you for the cost of your rental car if your insured vehicle is in the shop or is unavailable due to an accident. You need to have comprehensive and collision on your policy in order to add rental car coverage. In certain states, Esurance offers CarMatch Rental Coverage®, which covers the rental cost of a vehicle comparable in size and body type to your regular ride.
