Ford car range (6)
I believe the answer is:
sierra
This could be a double definition.
'ford' is the first definition.
(Ford Sierra is a car)
'car range' is the second definition.
'sierra' can be an answer for 'range' (mountain range). I am unsure of the 'car' bit.
Can you help me to learn more?
(Other definitions for sierra that I've seen before include "letter read out on the radio" , "Mountain range in Spanish-speaking countries" , "mountain area" , "Mountain range -- code word for S" , "- Nevada, Spanish mountain range" .)
