I’ve had pressed metal plates and 4D acrylic plates fitted to my cars over the years.
I used to get the pressed metal plates from Dub Meister in the past, but since lockdown I have been unable to get them to reply
I went for 4D acrylic this time from Number1Plates - they used to be a sponsor on here and offer 20% discount.
@Syphon might be able to confirm if this is still the case, as I can’t find them on here now.
I can’t fault the quality - I have a set of 400mm short plates on one car and standard size on the other with plate surrounds. Only issue is that in some modern car parks the ANPR cameras do not pick up the plate, which can make it difficult to pay/use automated parking. Both cars have passed their MOT recently as compliant with BS1045e and never been pulled over with pressed metal or acrylic 4D plates.
I struggled to get the plate surrounds onto my Cupra on the rear bumper as the indentations on the plastic trim did not align with any of the holes on the Wurth plate surround that I had.
Not sure if you want a country marking on the plate. If so, make sure it is one of the home nations or UK (not GB any longer) if you intend driving on the continent without a UK
sticker.
In terms of showing what the plate looks like you may struggle as peeps generally don’t wish to show their registration mark on here due to cloning/security.
Have a look at the company websites though - there are some Cupras on there.
