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.
