<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">certain car deal</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for lease that I've seen before include "Rent (a property)" , "Rent -- easel (anag)" , "Contract to rent" , "Contract for, say, use of building" , "Let; rent" .)
