Company cars wrecked crossing international region of France (7)

I believe the answer is:

corsica

I'm a little stuck... Click here to teach me more about this clue!

'region of france' is the definition.
'Corsica' can be an answer for 'region' (Corsica is an example). I'm not certain of the 'of france' bit.

'company cars wrecked crossing international' is the wordplay.
'company' becomes 'co' (abbreviation).
'wrecked' indicates an anagram.
'crossing' means one lot of letters goes inside another.
'international' becomes 'i' (abbreviation eg in IMF).
'cars' with letters rearranged gives 'rsca'.
'rsca' placed around 'i' is 'rsica'.
'co'+'rsica'='CORSICA'
