What was the first company to make cars?

There's no single definitive answer to the question of who made the very first car, as it depends on how you define "car." However, Benz Patent-Motorwagen built by Karl Benz in 1886 is generally considered the first practical automobile. While other vehicles with internal combustion engines existed before, Benz's was the first to be designed as a self-propelled vehicle for general use.
