Passenger vehicle available in manual and automatic (6)
I believe the answer is:
landau
'passenger vehicle' is the definition.
'landau' can be an answer for 'vehicle' (landau is a kind of vehicle). I am not certain of the 'passenger' bit.
'available in manual and automatic' is the wordplay.
'available in' says the answer is hidden in the clue.
'LANDAU' is hidden within 'manual and automatic'.
Can you help me to learn more?
(Other definitions for landau that I've seen before include "Old-fashioned four-wheeled covered carriage" , "Horse-drawn, folded-top carriage" , "Four-wheeled horse-drawn carriage" , "Old four-wheeled covered carriage" , "A four-wheel covered carriage" .)
