You’ll hear people saying they “ordered” a Toyota. They either have no idea what they are talking about or are simply trying to impress people. No one can order a Toyota. Dealers are given allocations for vehicles that are configured in such a manner that Toyota feels will sell in that region. Dealers can swap allocations if desired. Toyota has their production/assembly line to build x amount of vehicles in a certain configuration before they change tooling, add different parts etc. To build a vehicle per customer request would interfere with their production. Toyota is responsible for creating lean manufacturing, the model which most modern factories attempt to follow. Very efficient model. They try to forecast what their customers will buy. If they don’t like it they can order a ford.
