Definitions

There are a number of slightly different ways people describe or judge these terms. These are generally the most common categories. It does vary online but hey this is a start...

• Vintage Cars
  Vintage cars are built between 1919 and 1930. The term is often used to describe any car made before World War II. There can also be an overlap between vintage and antique cars.

• Antique Cars
  Antique cars are vehicles over 45 years old. Usually these cars are kept or restored to an original state.

• Classic Cars
  These are cars and trucks over 25 years old and less than 50 years old. In general it is typically a  car that is no longer in production and still popular.
  
  
• Hot Rods
  This is defined as a classic, vintage or antique car or truck that's been modified for looks and performance, usually repowered.

• Pickups / Trucks
  My favourite category, pickups and trucks! Good old workhorses! Simple!

• Buckets
  These are often used for true and replica t-buckets and similar styled vehicles.

• Rat Rods
  Rusty, bare metal, hanging together, build with scrap and old mismatched parts. Mostly not street legal, home builds and high performance dodgy rods.

• Old Racers
  These are often beach and track race cars and trucks, mostly dedicated racers and older vehicles. 
  
  
• Custom / Concept Cars
  These are more highly customized cars and trucks, not just hotrods. Often used to describe really unusual and impressive vehicles.

• Kitset Cars
  As it says, these are hobby cars, kitsets, homebuilds etc.
  
  

How does NZClassics sort groups?

Obviously that would be a lot of groups and categories to manage, but it would also make it harder to find cool rides, so I've simplified the categories.

  Roughly from 1950-1990 with exceptions for interesting cars.
