I'd say, get the running board.

I don't have it, and without it, it's very hard to get in and out....

It's only $300, nothing compared to the $50,000+ vehicle cost.

I'm going to add a few options a year later, and that includes $300 running board if ordered from the factory, at $600+....

And the 6 disc changer, titanium grills are on the list so far.
