Demand is high for both new and used EVs in Norway.
EVs are free (or significantly cheaper) on most toll roads, parking, and pay at most 50% of regular fees for ferries.
Owning an old short range EV as a second car can easily save you 1800€ a year[1] in toll fees alone. Even an old electric wreck is easily worth 10000€ just in reduced toll fees if it's able to do 5 more years of just rolling past that toll station barrier. Even banged up and with a 50% degraded battery the car is still valuable, as long as it can get you to work and back home again.
There was a time some years ago when you could essentially cover the down payments for a Tesla Model S from saved ferry fees if your daily commute crossed Trondheimsfjorden (cost like 30 USD per way, this "bug" has since been fixed, you now have to pay 50% of the ticket).
There is certainly a strong market for secondhand electric cars - I own one and it's the best car I've ever purchased. In terms of the "starting as low as 2000€", though, no. The battery alone in any usable electric car is likely worth more than that.
About the battery... Does that mean electric cars should have much better short/medium term depreciation and probably worse long term (as the batteries become too degraded for reuse)?
