Car with a three-box design (5)

I believe the answer is:

sedan

(Other definitions for sedan that I've seen before include "Covered seat carried by bearers" , "Covered chair carried between poles" , "Palanquin; car" , "Old carrier chair for Danes" , "Enclosed chair" .)

I've seen this clue in The New York Times.
