Who made only 50 cars?

There's no single definitive answer to "Who made only 50 cars?" because many small manufacturers, coachbuilders, and even larger companies have produced limited runs of 50 or fewer vehicles throughout automotive history. To answer this, I'd need more specifics, like:

* Time period: Were these cars made recently, or decades ago?

* Type of car: Were they concept cars, race cars, luxury cars, or something else?

* Location: Was the manufacturer based in a specific country or region?

With more information, I could provide a more accurate response.
