Damaged seat on British motor car that can be very noisy (5,5)

'motor car that can be very noisy' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?

'damaged seat on british' is the wordplay.
'damaged' is an anagram indicator.
'on british' becomes 'morgan' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'seat' is an anagram of 'stea'.
'stea'+'morgan'='STEAM ORGAN'
