Opinions are running the gamut.
For a newer vehicle with a good battery, RonRizz has the right idea, ie, not much is required. But, IMNSHO, it's not overkill to use a battery tender, crank it up every month or so (as long as you get it up to temp plus 5-10 minutes more), fuel stabilizer, &c.
It may be just a car, but it's a nice car that deserves a little pampering.
YMMV
