Since the advent of the wheel, there have been those among us who feel the need to take the design one step further. Some do it for speed, some for handling, and some simply for style.
The result? Vehicles fitted with neon underglows, spinners and headlight eyelashes, to name a few. Install the wrong optional extras, though, and it could be a crime of more than bad taste.
Certain modifications may be deemed illegal by your state authority, so it pays to check before you drive. Other car mods made without your car insurer’s consent could void your policy, while some can put a dent in future resale value or even turn away potential buyers.

Car insurance policies can differ dramatically in what is covered and also in price, that’s why it’s so important to compare policies and read the product disclosures before signing up.
It’s also part of your duty of disclosure to tell your provider immediately when you decide to make modifications to your car. If you don’t, by law your provider may reduce or refuse your claim or cancel your policy.
