I have a 1989 Honda accord and want to know all the benefits of this car gas mileage etc, and what are the steps to start driving legally

By benefits I mean what you like about it or things i don't know and awesome cool things other people wouldn't. Know thanks.

That car is about ready to go to the scrapyard. There are no benefits.

There's nothing special about a 1989 Honda Accord, short of the hide-away headlights. The main thing is that is likely quite tired and near ready for the crusher.
