Gotta be clearer about the "reset" thing. When you remove battery for just a few minutes the PSM has to be reset and you can do it yourself by driving (I've done it). If it doesn't work *as described in manual* dealer is required. I would want to know what ELSE exactly needs to be reset, presumably by the dealer only?
Make sure you follow instructions for long term storage, full gas tank, new oil; there're websites devoted to this subject of LT storage.
I'd just slap on a battery maintainer and have someone check the battery's electrolyte level in a month. Also follow guidelines of LT storage for other aspects of the car.
