If you intend to alter your vehicle in any way that makes it different from the standard model, which includes adding non-standard accessories, you will have to contact the insurance company. You will have to provide your insurer with a list of the alterations and accessories along with their monetary value. You also have the option to remove alterations and accessories from your policy by contacting the insurance company.
Step 1: Gather your information. To obtain a quote you will need birth dates, an email address, and a previous address in most cases. Also, know what type of car you are driving. This is more than make and model. Know what trim package you have, etc. These little things do matter. If you are currently insured, having your policy handy is not a bad idea.
