i realize this topic is a never-ending one, but i wanted some advice from some of you with way more knowledge than i. i keep hearing about imminent things coming like Heads-Up Display. "Spaceship Controls" is coming. new paint options are coming. armrest/2nd row console? i want to order a P100D, but i have another sweet car i'm using now so i am in no rush (other than i want it badly). do you think now is a relatively "safe" time to buy? or if you were me, would you wait because there's a feeling that upgrades are coming soon? and yes, i know that no one knows definitively, Tesla keeps everything secret until it is revealed. but i wish we had some sort of "Buyers Guide"... kind of like macrumors.com has for Apple products. they show how long it's been since a product has been updated and give general "good time to buy / caution / don't buy, wait" recommendations. iPhone, iPad, Mac Buyer's Guide: Know When to Buy thanks in advance for any input you might have!
