Hi there
I don't think used cars will ever get back to the lows of pre pandemic. Will they drop back somewhat, seasonal effect aside, yes I think some cars certainly will drop back, especially when new car delays are no longer an issue. However I think this really only applies to more generic cars, like city cars, high volume models etc.
Anything that is slightly collectable or special I feel such cars will remain firm and potentially continue increasing as they are cars that many petrolheads aspire to own or have been a dream car. Also factor in all the 20-30 year olds currently who had a Lamborghini or Ferrari poster on their walls, in 5-10 years some might be in a position to buy and with very limited stock available the prices will be high.
EV cars no matter how fast they are, to me with what is currently available I find them absolutely boring to drive, they have absolutely for me just a tool to go from A to B, I may even consider an EV myself but not because it is fun to drive or I have a passion to own one but simply because in the future it may make financial sense to own one, such as free charging at work or if fuel cost £3 a litre etc. For me nothing can compare to the excitement an ICE car can give just by starting it up, just by looking at the masterpiece of the engine under the bonnet and of course been able to tinker and do DIY on my own car in my own garage. You cannot tinker with an EV, you cannot service an EV except for making changing the disc and pads plus topping up washer fluid. As a work tool, financially an EV makes sense, as an object of fun that creates excitement and makes me grin well ICE all day long, I find a rusty old MX5 a lot more fun and to drive than what an EV can offer. I am not alone in my thoughts, millions of petrolheads out there who think alike and it is why all the cars of the 90's are pretty much gone, bought up what was left and locked away in peoples collections. You can see it happening over the past five years certain models of cars available reducing in numbers, even more so now.
So if its a petrol head, enthusiast, collectable I only see prices moving up or at least holding firm and any price drop that does come will be next Winter now or into 2023 and I mean actual price drop, not the usual seasonal drop.
