After dreaming about getting a MS for several years, 2016 was going to be the year that I finally made that a reality. I had a plan to order in October and take deliver in December on my birthday. I had the specs of the car all planned out too. Deep Blue Metallic, Grey Interior, Pano roof, Auto-Pilot 2, and hopefully 100Kw battery (based on Elon's stated improvement per year). But in the age old words of John Lennon, "Life is what happens when you're making other plans" and instead of taking deliver in December I was only placing an order in December. Things on the car had also changed by the time that I got to put in the order. The Free Unlimited Super Charging that was always a part of the mystique of getting a Tesla was going to go away on December 31. So to preserve that I ordered a 90D but purposely pushed out the delivery date in the hopes that the 100D would become available and that I would be able to upgrade like the folks in the queue for the P90D did when the P100D came out. Now I live and work in Michigan, and it's a strange thing to try and buy one of these cars in a state that is actively trying to discourage you from doing that. You can't buy one from a store here, you can't test drive one here, heck they won't even let Tesla open a service center here. But I did get to test drive the car three times, once in Cleveland, once in Toledo and once in Cincinnati. The unfortunate part there is that I don't feel like I have a specific Tesla OA that I've been working with long enough to establish any type of relationship. So I can't easily go to them and ask my questions. Which is why I greatly appreciate this forum. Now that you've got a little more context, here's my dilemma. My plans for the Tesla were to buy it and drive it a lot. I want to take long road trips and cruise the country. One of my big dreams on the bucket list is to drive "around the country" in one go. To Washington state, California, Florida, Maine and then back home (best I can figure that's about 8800 miles). Having a 100D would be nice for this because for a few big reasons, first I'm all for sometimes taking the road less traveled and getting off the highways and exploring. More range equals more opportunity to do that. Also, the out and back trips from a SC would be easier with more range. For example we don't have any SC's in the UP of Michigan now and so it would be difficult to drive up there w/o significant planning. There's also range degradation and winter that concerns me on a car that I'm planning to keep for several years (have had my current car for 10 years now). The 90D on order that will be delivered next month (which has a VIN but is not yet in production) would have the Free unlimited SC but, 100D is so tempting. Unfortunately if I do switch though I'll likely end up at the back of the line again (meaning a March or later delivery) and then I'll also lose the vented white seats, which are an OK substitute for the grey I really wanted. But I really don't think I want solid white seats. Decisions, decisions... I'm just stuck right now not sure what to do. Ideally I'd take both...and that's what's odd about this whole thing is that I don't want the 100D upgrade for free, I'll pay for it...gladly it's just unfortunate to be told that I can't get it without giving something else up that I really want too. I appreciate the advice from any that managed to read this far. Sorry for the length of the post...but perhaps just typing this all out will be a bit cathartic on its own.
