Specialty Auto Insurance

It’s More Than Just a Hobby.

Whether it’s an antique, a collectible, or your own custom-built roadster, your Specialty Auto is a labor of love. If you’re like most enthusiasts, you’ve poured many hours of time and effort into making your auto something unique and special. At GNB Insurance Agency, we realize that when you’re cruising down the strip, speeding across the track, or making heads turn at a show, the last thing you’ll want to worry about is whether you have the right insurance.

We believe that your specialty car is not only a major investment, but also an extension of you. And a vehicle as unique as its driver requires more than a standard insurance policy. That’s why we’re proud to offer a variety of specialized coverage options for the following vehicles:
  • Collectibles
  • Antique and Classic Cars
  • Hot Rods
  • Custom-Built Cars
  • Show Cars
  • Race Cars
With options and choices ranging from agreed value coverage to spare parts coverage, GNB Insurance Agency can provide you with the tools you need to insure your timeless automobile. We even offer multi-vehicle discounts for the avid collector.

Whatever your situation, you can rest assured knowing that your Specialty Auto is protected with GNB Insurance Agency.
