I know that some may think this a luddite philosophy ......... But I like to minimise the size and visual impact of my tax disc holders.
I have gone old school in my cars. If you go to grotty looking car spares shops they still sell loads of items that are made in Britain like proper Jubilee clips, not the nasty copies
They also sell made in England tax disc holders for about £1 and they come in really basic colours.
Plain black to blend with dashboard. The rim is clear to minimise visual impact. Lick to adhere. It stays put yet still comes off easily every year. Very hard to beat in my opinion. And it takes you back to your dad doing this in the 1970s
I absolutely despise the dealer fitted ones that use glue and took all dealer transfers off mine on day one and used solvent to get the glue off. Halfords only sell blingy ones and ones that use glue
The only thing better than this I have seen is a very thin stainless one sold by Audi, but this has the 4 rings on it. You put a hollow black circle on the screen that was magnetised, and the holder stuck to this. Very simple, very useable, very slim, unlikely to be seen and stolen by chavs
