Maybe it’s because your stickers are so expensive.
My annual sticker is only about 52 Pounds (Is that how I say it?) of your money. $80 Canadian.
The Stickers go inside the windshield to help stop theft.
The plates are mostly stolen for unregistered or non insured vehicles.
I was examining what 'would' happen here, if the stickers where added to the plate as 'you' do, to create a really tempting object on the fender. (Bumper)
Pounds or if you want to go native: Quid.
Mine is only £32. Diesel low Co2, madness.
