That’s Just Cute
Cars are given names and people often identify the car’s capabilities based on those names. For example, Subarus are known to be good cars for the outdoors, particularly places with a lot of snow. As such, they have names like Crosstrek, Outback, and Forester.
This very sweet and naive person thought the name of her car, City Golf, implied she was only allowed to drive it in the city. So, after leaving the city for only a short period of time she became concerned and took her car straight to have it checked out. I’m not sure I could’ve stifled my laugh if I were that mechanic- so sweet!
