Chas F: When you get back from the cruise could you provide some of the decision points for adding the Tech Package? Charlene and I have it in our design studio reserved car however, I consider it expensive for not much real advantage. What made it worth the expense for you?
As it turns out, we have WiFi on the ship! ( I know...this is sad)
To be honest, I have never been able to rationalize that the Tech Package makes financial sense. I've posted my thoughts on this on a separate thread (is the Tech Package really worth it?). It sounds like you are in the same place I am (expensive, not much value), but there are two things that pushed me over the line:
1. Though I can afford a fully loaded model S, I have a mental $ threshold that I just am not comfortable crossing for a car. When I thought supercharging was included in the 60Kw MS, I decided to go with it for all the advantages that come with the 60 Kw but the tech package was just an unnecessary expense that became an easy drop. When TM announced the $2K additional charge to enable supercharging, this crossed my threshold again and I dropped back to the 40 Kw pack, where I originally started. With respect to my "threshold", I now have $10K of discretionary cash and feel like I can afford to splurge on the Tech Package.
2. At my test drive in Dania Beach, I asked David (store assistant manager) to "sell me" on the tech package. He ran down the usual suspects and didn't really sway me. Not his fault, there was just no new information there for me. As others have stated, the HID lights and Nav are really the biggest drivers, but I don't have Xeons now and wouldn't miss them and I have sufficient Nav on my iPhone for what has now become only a commuter car. So, I only needed a reason to go for it...if only a small one (because of #1). Turns out, it was seeing the fog lights in person that pushed me over. I know it seems trivial, but it was one of those things that I decided that day that I wanted and couldn't easily retrofit more cheaply.
So in the end, a lot of little things added up for me to add the Tech Package: $10K of discretionary budget, nagging worry that I would regret not getting it in the future for some unknown reason today, completion of a premium car (it really should be included), fog lights, enjoyment of all the remaining features over my expected 10 years + of ownership.
Hope that helps.
