Yup, all true 04s were a Limited with an auto day/night mirror but they were not called LImited. In 05 they took away the auto mirror and called it a limited and introduced a Base model with black paint, manual, and a LOT of stuff missing - but still the same engine and drive train....

Dave's link spells out all of the differences 'tween Base and Limited.

My car in the pic below is a "Special Edition" Roadster - that is, a Base with Red Paint, satin side stakes, really cool SRT like wheels painted Gray inside and satin door handles and the OPTION of an auto transmission.
