2. There's no reason to believe used ICE or Hybrid vehicles are going to drop significantly in price in the near future, unless you believe that driving them or selling gasoline is going to become illegal or something (lol).
There are recent reports in the UK of the opposite happening. Second hand hand car prices have been elevated for the past couple of years, due to the constrained supply of new cars. Now that is ending, prices are falling but second hand EVs are falling much faster than ICE cars. That might be temporary. Current high electricity prices, and poor public charging infrastructure, are definitely working against EV uptake at this moment, but I assume that will change.
I never compare to the UK used market. As a country who drives on the left, their cars are basically useful in the UK and Ireland who makes their used price to he a lot lower than cars in countries like Germany or France.
Most of the second hand Mercedes, BMW and Audi in circulation in Portugal were used 4 years, diesel with close to 200K on the odometer, although some sport petrol ones as Audi S4/S6, Mercedes SLS and BMW M3/M5 are also originally German imported.
A ton of classic cars and exotic/sports cars (as Aston Martin, Renault Clio V6, Nissan Skyline R34, Honda Integra, Mazda RX7) are UK imported and legalize in Portugal because of their price being in some cases close to 40% less (even after taxes and registration fees, if their original registration is before June 2007) than the equivalent left hand drive already in the country.
That's why in Portugal it is common for people who want specific models or classics, who mostly will be on a garage 95% of the year go to the UK and then import and register them in Portugal.
Or if they want a German car to go to Germany and Import them.
All of this to tell you that in terms of prices in Portugal EVs used and Hybrids didn't had a significant drop in value compared with pure ICE models.
