I think it is more likely that second hand EV prices have fallen in response to Tesla's price drop and increased supply. A significant proportion of used EVs are Teslas and when the new price drops by over 10% that immediately means used prices have to drop by that much. Long waiting times also meant nearly new used cars were more expensive than new, which was never going to last. Put the two together and the 9% fall is entirely reasonable.
I wouldn't read too much into VW's efficiency gains. Motors are already 90% efficient or more, so a 20% improvement is really at most a 2% improvement with added marketing. Nice to have but nothing to get excited about.
