a lot of cars rapidly depreciate in the first year. A model S losing almost half its value in a year or so is no incredible shock.

Especially now that the perf option used to cost twice as much (now the uprated brakes/wheels are part of the perf package). Now autopilot (not FSB) is included. Also the new motors mean 370 mile range is available with the 100 kwh battery. AP3/HW3 is also now shipping as standard.

So yes the rapid progress means that the older cars depreciate quickly. This is only get worse with the next refresh rumored to be fairly soon.

Last year this time some of the same models selling for $40k in the used market were $80k. These were for some of the oldest cars in the pre-owned segment.

The biggest hit to value came with the Tesla price lowering.

Id expect a 20% loss but not 50%. Porsche and Lexus don't lose 50% the first year.

I have a 4 year old s85d. A year ago I got an offer to trade in for 50k from tesla. I bet the value went way down because My ~260 range is so much less than 370.

Don’t understand the downvotes? Not original poster so I hope I can bring this up.

Commenting on year 1 depreciation is like commenting that 2+2=4.
