"Even outside of cars, if you haven't noticed my writing is not really superb!!"

I would take issue with that. Your writing is concise, well organized and grammatically acceptable to the forum in which it is being presented. In my real job years ago, I supervised a herd of engineers.

Some of the most talented engineers could not describe the process of pouring body fluids out of a boot and as a result, many of their great ideas and solutions would be passed over in favor of lesser ideas that were better described by another engineer.

The solution to that was to assign a great writer to help the brilliant engineer (and then to get both of them to admit that they were good at different things).

Keep on Jeepin' and keep on writing.
