Charging System & Battery

I looked through the archives and couldn't find a definitive answer to what I am looking for so here it is. I am looking at buying a coupe CC and it will probably only be driven once a week for maybe 50-100 miles. How is the charging system and battery longevity of the Maser? I have had cars in the past that did fine with this and others that did not (those that did not I kept a trickle charger on). Any insight appreciated.
