According to dict.cc, Golf can mean the following:
(das) Golf = golf [sports]; der Golf = gulf; bay [geogr.]; der Golf = abbreviation for VW Golf
There is also a separate entry for Volkswagen Golf with a rather weird English translation:
(VW) Golf® = (Volkswagen / VW) Rabbit® [USA/Canada] [automot.]
So, what's the association that a native German speaker has with Volkswagen Golf: Is it with a game of golf or with an animal? Or is Golf just a brand name without any associations?
