Wife and I took our Z from St. Louis, MO to Quebec City.

My advice for long distance in the Z.
Bring a butt pad. After a while the Z's seats will kill your ***.
Soft cooler bag fits perfectly on the shelf behind the seats.
Bring a can of good glass cleaner, microfiber, and paper towels for bug cleaning.
We were getting 27+ MPG, so your range should be killer.
