Some land beyond London area - alternatively, a car (7,7)
I believe the answer is:
chelsea tractor
'some land' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'beyond london area alternatively a car' is the wordplay.
I cannot quite see how this works, but
'beyond' could be 'else' (I've seen this in another clue) and 'else' is located in the answer.
'area' could be 'tract' (tract is a kind of area) and 'tract' is found in the answer.
'alternatively' could be 'or' and 'or' is located in the answer.
'a' is found in the answer.
The remaining letters 'ch' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for chelsea tractor that I've seen is " Huge 4WD".)
