And to be honest, I don't know that I have the experience to evaluate the acceleration at higher speeds. I've said many times that were it not for what others have written, I would never have known there was an issue.
On the other hand, I --DID-- know that I was buying a really powerful car. I knew how happy people were with the performance of the P85, and I heard Elon Musk say during the D announcement, which I watched many times before ordering, that the P85D would have "half again as much power" as the P85. So while the numbers didn't mean anything to me, since the P85D was my first sports car and I was by no means a sports car enthusiast, the concept of a car that was going to be 50% more powerful than a car that I knew people were thrilled with --DID-- mean something to me.
So now, knowing that Tesla did not deliver all they promised is upsetting to me. The issue was just amplified when Tesla announced the Ludicrous upgrade, which to me, and many of us, seems to be a way to charge us for making the car more like it was supposed to be when it was originally delivered.
If you've ever shopped for a reasonably high end diamond engagement ring you know about the 4 C's--Carat, Cut, Color, and Clarity. Carat is the size, which you can see, to an extent. Cut refers to the shape of the diamond--round, rectangular, etc.--but there is also a quality component in the cut as well. Color actually for the typical white diamond really refers to a lack of color--the less yellow the better. And clarity refers to the imperfections (or lack thereof) in the stone.
I'd be willing to bet that unless you have training in this field if you were in the market for a diamond in the 1-1.5 carat range, and in the $25,000-$35,000 range, someone could easily show you a $25,000 larger diamond that would look better to you than a $35,000 smaller one. In other words, you would not be able to get even a reasonably good idea of the value by just looking at the diamond.
Take this a step further. You decide to pay $35,000 for a diamond that you believe to have x,y, and z characteristics. You find out later that the diamond doesn't actually have those characteristics. You can't see a difference. Are you upset?
That's kind of where I'm coming from.
I really like to get what I pay for. This is less important to me, obviously, when I'm buying a $20 item on Amazon than it is when I'm spending $140,000 on a car. In the latter situation, I REALLY want to get every penny's worth.
