I'm sorry O_K but "beggers can't be choosers"
Meaning, she has dibs on her car, no matter what.
She is doing you a favor by letting you use it at all.
And if your grandma doesn't like you using hers,
then it has come time for you to get a car of your own.
Having a car is more practical, especially if you are getting older.
These are the things we do as our world, responsibility & needs grow.
You might have to get another job to suit your growing needs.
Shit, I remember having 3 jobs when I was your age, I only got 4 hrs sleep a day.
(JCP shoe sales, Subway & a graveyard shift gas clerk)
Such are the sacrifices we make for "keeping up with the Jones"
I know...you hate cliches.
