<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">saloon car</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for sedan that I've seen before include "Andes (anag.)" , "A closed litter for one passenger" , "big chair" , "Type of chair that's carried" , "Saloon-car" .)
