True. Many Classic insurance companies limit your miles. However, Hagerty does NOT. You are at your leisure to drive it as much as you wish. But, it cannot be your primary vehicle and you must prove such by providing a copy of the registration for your primary.
On the antique tags thing, every state is Different. My home state of AL, states that If it has the antique plate, it can only be driven to and from a repair facility or in a parade or show. However, other states are diff, some allow unlimited usage. Hagerty as well as a few other classic insurance providers are working with various states to get that changed. And they have, they update on this topic quite often in their quarterly new letter. Some states now allow for weekend driving and occasional use, outside of the parades/shows/etc. Other than the novely of having that Antique tag, the only thing gained by having it, is the fact that you dont have to re-register every year, and pay that annual tag fee.
On the actual value....Once agian every Company is Different. Hagerty, will allow up to the NADA classic value, IF your pictures clearly depict that its in claimable condition. If you wish to go higher then you will need to provide reciepts for big ticket items, say a crate engine or transmission, or any high $ addons. After that, yes they may request a formal appraisal.
On loan values.....yes there are Collector vehicle loan places out there that WILL loan against the collector vehicle value. And at rates not much diff than what you woudl get at any bank anywhere. How do you think people manage to buy that dream car that is now valued at 100 times what it was when it was made? If nothing else thank the muscle car craze of the past 10-15 years for all these nice available amenities.
Ive more than once ask hagerty how they manage to keep such low premiums. The answer basically was...." We dont get very many claims. We have found that people who own collector cars are a different breed of driver/owner. Most care more for their vehicles than they do their young."
