Busted open (lead-free) car's struts (7)

Ross

I believe the answer is:

prances

'struts' is the definition.
('prance' can be a synonym of 'strut')

'busted open lead-free car's' is the wordplay.
'busted' indicates an anagram.
'lead-free' means to remove the first letter (the letter which leads the word is removed).
'open' with its first letter taken away is 'pen'.
'pen'+'cars'='pencars'
'pencars' with letters rearranged gives 'PRANCES'.

I've seen this clue in The Telegraph.
