Wow! What a lot of assumptions people are making. Anyway we will know the pricing before long.
Unfortunately I think the prices of the trads will start to fall for the simple reason that driving older cars will become more and more restrictive.
I think that the value of all ICE vehicles will start to fall as they fall out of favour with the public. Anything perceived as polluting will be essentially worthless in 10 to 15 years.
You haven't seen what people drive around in, in South Yorkshire.
Probably the same as what most people drive around in Gloucestershire: sub £2k snotters, old bangers that are essentially worthless, in the sense that if they go wrong they scrap them and buy another rather thna fix them.
