If this were a question on my test, I'd probably go for tolerant or sentimental. I'd probably go for sentimental, because if the sentence had a more tolerant tone, it would say something like "My car isn't the greatest, but I can live with it".
I would say either a free verse poem or a short story.
Free verse- You are not constrained to a meter and it doesn't have to rhyme. You can get your point across without limiting your thoughts!
Short Story- Your example can be taught in a fictional genre, a non-fictional genre and it can be as long as you want it to be!
Hope this helps!
