* Number of units produced: This is a key factor, but even if a car had a low production run, many could be lost or destroyed over time.
* Condition: A perfectly preserved example is rarer than a damaged one.
* Location: A car might be considered rare in one region but more common in another.
* Specific model variations and options: Even within a model year, certain options or configurations might be exceptionally rare.
Therefore, any claim of the "rarest" car is subjective and depends on the criteria used. Many extremely rare vehicles exist, often one-off prototypes or cars with incredibly low production numbers. To find contenders, you'd need to look at specialized automotive databases and collector resources.
