Lot choice (5)
I believe the answer is:
sedan
'lot choice' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sedan that I've seen before include "Palanquin; car" , "big chair" , "Type of chair that's carried" , "In cars, an alternative name for 'saloon'" , "Type of chair - battle" .)
