Hi all, most plods will not bother about german style number plates providing the colours are correct (i.e one yellow and one white with black lettering) and the format of the letters remains in the original pattern and the letters are clear (i.e H838 LSD not H8 38 LSD), It is also worth bearing in mind that the road traffic act and the MOT testers requirements do not match, for example if your car had purple and green number plates and the type spacing etc was correct it would pass an MOT but evidently you would get done for them, similarly if you have a particularly anal MOT tester they will fail your plates come MOT time so worth keeping the originals. As for not using them at shows that is utter b*llocks, you can put any plate on your car when it is not on a public highway as the construction and use regs and road traffic act clearly do not apply, and no you cannot register your car in Germany without a German address and even then you can only use the plates outside Germany for a limited time. and the police NPR systems will still pickup a german plated car, Hope this helps
