Our fully-optioned Model X P100D was purchased in June 2017 for $334K. A new equivalent today is $208K.
Sure it's $126K less, but most people buy Teslas as a means of transport favored for individual reasons (such as enjoyment, performance, features, environment etc), as opposed to thinking of them as an "asset". Our assets are concentrated in brokerage accounts, not things that require concentration as you drive the kids around. We had our last car for 14 years and find if you treat them well, they'll treat you well, and it doesn't really matter what the original cost was.
The positives of this price drop for me are:
* A much wider audience of people can now afford them and enjoy the very different ownership experience vs ICE
* Being less "elite" means fewer people will maliciously damage them or complain about "avoided" fuel taxes etc
* It's cheaper for us to replace them as they age
* It'll become cheaper to insure (as more will get written off than suffer ridiculous repair bills)
I probably would be more tolerant, though still very annoyed, if I kept all of my cars for 14 years as well. In reality cars have always been my "thing", I've owned a lot of them in my time and I tend to change them every 2-3 years. It is rare for me to keep a car for much longer; but I've owned one car for 33 years and counting and there have been a couple of others that have hung around for 5-10+ years; but that is very unusual for me. Hence my obvious annoyance at the unexpected and unpredictable depreciation of my Tesla's. Maybe I'll just hold on to them and give them to my kids when they are old enough to drive
