1. How often will you be driving the car. Just weekends? Only in the summer? Or everyday? This is another large factor. Know that in the event that anything goes wrong, your insurer will check the the mileage. Deliberate over-use on a light policy could nullify your policy, and fixing these cars out of pocket isn’t cheap. Most insurers offer packages ranging from 1,000 to 6,000 annual mileage.
2. The type of vehicle. is it an antique, Custom, Exotic, Street Rod?
3. Membership to a prestige car club. Believe it or not, many insurers give discounts based on membership to a car club. As far as their actuarial tables are concerned, it shows an added level of responsibility and commitment to taking care of the asset.
4. The type of coverage that the insurance company specializes in. A broad market insurance company may use high prices to discourage customers from taking luxury policies that they are not equipped to manage. Look for an insurer who specializes in your type of vehicle. Most of the insurance companies who handle classic and collectible cars provide service for new exotics. Luxury car insurance rates typically run about 20% more than traditional policies.
5. An agreed upon value. This is unique because traditional insurance policies provide coverage on the Kelly Blue Book listed value, which does not consider the value of antiques, after market modifications, expensive stereo system, and a variety of other attributes that make your car more valuable than the standard tables are capable of estimating.
6. In addition to standard insurance options (like uninsured motorist, bodily injury, PIP, etc.), your luxury coverage may also include:

• Glass coverage is also very important windshields are prone to cracking, and can be very expensive to replace given the scarcity of parts with collectibles and exotics.
• Accessories should also be included. It may not sound like much, but car covers can be stolen easily and are surprisingly expensive to replace.
• Speaking of things being stolen – having a good security system will also improve your rate

Where to find Luxury Car insurance? Start with your auto dealer.  Then check out the back of Car & Driver, Hemming’s Motor News, or the Robb Report, where they typically advertise. There are a bunch of websites that claim to offer it as well, as always you should exercise caution before submitting any personal information online.

Drive safe and have fun!
