I love Tesla and love my p85 delivered just a few weeks ago. But I cannot help but feel some regret in my purchase as I would surely have purchased the D if I knew of its arrival. I live in a snowy climate and am a bit of a performance geek and I try to be savvy in relation to depreciation and purchase price. historically, when purchasing cars you always knew where you stood in the upgrade cycle. If you bought on release date date you knew the car would be unchanged for at least a year and you also knew roughly when the new cycle would begin. You also knew that negotiations would be tight. Conversely, if you bought at the end of a cycle you knew that your car would change rapidly, depreciate quicker and that a dealer would negotiate more in an effort to "clear the old model." i appreciate Tesla's efforts and respect their marketing.... They have a car with high demand because it is a great product and they know how to show it off. But, I cannot help but think there is probably a few of us that feel a bit burned by the uprade cycle. If my salesman or the order website had given me a heads up maybe I would have waited the extra 60 days...maybe not. But it would have been nice to have a choice. I believe their are a lot of reasons why traditional car companies have a slower rollout process....one of those reasons may be that it gives the buyer a sense of choice which ultimately allows them to own the decision of waiting for the next best thing or not. Owning the decision means you can only blame yourself...not the car company. I Will continue to love my P85, but I suspect every winter morning will elicit a small curse toward Mr. Musk....at least until I hit the accelerator and my grin returns -- just not quite as wide as a P85d grin.
