I love can’t seem to keep my convertible running, one day it starts and after that it won’t, haven’t been able to drive it for over a year and the dealership that has been checking it since I purchased it says I just don’t drive it enough

 

Could easily be the cause. I found out the hard way. Within the first year of owning my wife's brand new 08 drop top we found it dead in the garage. 3 weeks of non use, dead. The owners manual clearly states what fuses to pull if the car is not used for a few weeks. The electronics in modern cars do drain the battery over a period of time, faster then one would think.

 

For not much money you can get a trickle charger that will keep the battery up while the car sits, without pulling fuses. I use one to keep the battery charged over the winter for my convertible.
