Steer left in the German car (7)
I believe the answer is:
daimler
'car' is the definition.
(I've seen this before)
'steer left in the german' is the wordplay.
'steer' becomes 'aim' (I can't explain this - if you can you should give a lot more credence to this answer).
'left' becomes 'L' (common abbreviation).
'in' indicates putting letters inside.
'the german' becomes 'der' ('the' in German).
'aim'+'l'='aiml'
'aiml' put into 'der' is 'DAIMLER'.
Can you help me to learn more?
(Other definitions for daimler that I've seen before include "A milder form of a posh car" , "German car pioneer, lead rim (anag.)" , "Make of car" , "Car manufacturer" , "Red Liam has a swanky car" .)
