Being German, he has a car (4)
I believe the answer is:
herr
'being german' is the definition.
(German equivalent to Mr)
'he has a car' is the wordplay.
'has' means one lot of letters go next to another.
'a car' becomes 'RR' (Rolls Royce).
'he'+'rr'='HERR'
(Other definitions for herr that I've seen before include "German form like Mr." , "A German gentleman" , "Form of address for German male" , "German man's title" , "Mister in German" .)
