What if their was same lower age limit for both Car or wheelchair (6 Years) but wheelchair had 14 years upper limit & car only had 10 years?
Sussex will get out his abacus tonight and give you the precise plate values
Seriously, though, these things are impossible to quantify, and it depends on the precise spec and numbers regulation in a particular council area.
But, generally speaking, restricted saloon plates always have a value where WAV plates are unlimited.
Or saloon plates will command a higher price than WAV plates if both are limited in number.
The precise values will depend on the precise vehicle numbers and vehicle spec in each authority.
And, in extreme cases, the basic rules of thumb might not apply.
For example, imagine an area where both saloon and WAV plates are restricted. But no age rules for WAVs, but saloon HCs require a brand new £100k EV, which has to be replaced after three years
Chances are, very few if anyone would want a saloon HC plate, therefore they'd be worthless.
Of course, in reality things aren't like that, and the basic rules of thumb apply.
And, as well as vehicle spec and restricted numbers, the values depend on driver attitudes. For example, Rashid seems to see WAV work as an opportunity, while I suspect many drivers pay a premium for saloon plates over WAVs to actually avoid wheelchair work
Likewise, many drivers see a WAV as an opportunity to carry more passengers, while one reason I avoid an eight-seater is the thought of eight pished up passengers in the back
But I wouldn't overthink these things. You seem to know the plate values in your local area, so whether you're willing to pay the price depends on your own personal preferences and dislikes.
I wouldn't waste time trying to work out the whys and the wherefores of how the different plates are worth what they are. It's just a rabbit hole that there's no real exit from
