Kept all of them on the 3 cars in my household.
Helps remind me of the month they will be due. (I do as few direct debits as possible.)

Never had my collar felt by the plod.

People who refuse to take time and remove their ancient invalid tax discs are usually demonstrating that they couldn't care less about their cars and fill their cabins with all sorts of other appalling rubbish.

I ought to take exception to that but I'm too thick-skinned to bother - my VED disk was still valid when the system was abolished so simply left on display - the car outherwise spotlessly clean and tidy.

Can I just reply that people who make random, stupid, sweeping statements usually talk through their adenoids, and go trainspotting ?

My apologies to trainspotters everywhere.

I stated why I kept my tax discs on the screen - I don't see a strong connection between leaving it on there and filling the car with appalling rubbish, although in my case the rear of the cabin is indeed full of awfulness: My kid simply has some kind of 'does not compute' thought-process when it comes to where to put half-consumed packets of sweets, crisps, sandwiches, ice creams, any kind of drink in any kind of container, fruit...
...and rhinoliths (which are INCREDIBLY difficult to remove from door trims).

When I was a child, I'd have got a darn good hiding for thinking nothing of leaving spilt sticky drink or ice cream all over the rear passenger seat for a 4-hour journey, but nowadays corporal punishment is a no-no.
But I'd never have been so unthinking as to leave it unmopped-up in the first place.
Must get it from his mother's side..
Hey-ho...

Regards that car's MOT - perhaps Mike Brewer bought the neglected vehicle for a song, realising there was a profit in it after minor sprucing and gaining a MOT pass?

Tax disc? I still have a yellow faded note saying tax in post! ;-)

My next door neighbour has a sticker on the windscreen of her car where the tax disc would have been saying "Tax Paid"!

Rather reminds me of the stickers people used to put on their cars in the early sixties saying "Ten Year Tested" when MOT tests were first introduced.

My Dad has every tax disc he's bought since he bought his first car in 1957.

And, he keeps a record of mileage between fuel refills - plus how much fuel he's used.

At 92, I suppose nostalgia is a good excuse!

My vintage car displays a replica of its first tax disc. Not an uncommon thing for owners of old cars to do. The only thing that is wrong on mine is it shows the Horse Power which is a deliberate wind up to owners of four wheelers as the 10 hp (RAC) of it had no effect on the tax which was £4 a year - for a tricycle. Road Fund tax (it's old enough) for a four wheeler with that engine would have been £10.
