Who sold the first car?

There's no single definitive answer to who sold the *first* car, as it depends on how you define "car". There wasn't a sudden jump from horse-drawn carriages to modern automobiles.

However, Karl Benz is generally credited with selling the first *practical* automobile. He sold his Benz Patent-Motorwagen in 1886. While others had created self-propelled vehicles before, Benz's was considered the first commercially successful automobile.
