Here's why it's hard and some examples:
* One-Offs: Some cars are truly unique, built as prototypes or custom creations for specific individuals. There might only be one of them.
* Limited Production Runs: Many manufacturers have released limited edition models in small quantities, often in the hundreds or even thousands.
* Lost Cars: Sometimes, cars are lost to history, making it impossible to know how many were originally made.
To give you some examples of very rare cars:
* The 1934 Duesenberg Model J "Mormon Meteor": This was a custom-built car with a massive engine and unique design. It's the only one of its kind.
* Ferrari 250 GTO: A legendary race car, only 39 were ever built, making it one of the most expensive and sought-after cars in the world.
* Ford GT40: Another famous race car, with just over 100 built.
* Pagani Zonda: While not technically only four, Pagani produces very limited numbers of their hypercars.
It's important to remember: The exact number of cars in existence can be hard to verify. There's always a chance that more examples will be found or that some have been lost over time.
If you're looking for a specific car with a very limited production run, you'll need to do some research on that model!
