In the world of automotive, classic versus antiques versus vintage monikers are used interchangeably. Some classifications can even overlap. And it might not seem important to know how your old-looking vehicle is classified, but it does make a difference.
In terms of title and registration, not to mention insurance rates, depending on where you’re driving that car. Different states have different classifications; for example Texas requires a safety inspection, an emissions requirement, a title, and even has sales tax on older cars.

Generally speaking, a classic car is a vehicle that’s over 20 years old. An antique car is over 45 years old, while vintage cars are built between 1919 and 1930. But depending on the state’s DMV, and even on insurance carriers, classification can change and titling and registering can change too. That’s why it’s always a good idea to check on your state rules and regulations.
A classic car should have been repaired and maintained to keep it looking like the original design and specifications. It shouldn’t be modified or modified. A vintage car on the other hand can be modified and still keep its moniker.
