Australian Capri owners ( and others) are probably lucky (I guess) - so far - that the facility isn't available for the Aust ID plate - take a pic of a tag, replicate it - and off you go? Anyway, an ID plate OBVIOUSLY - isn't the last word - when it comes to authenticity. ( especially a UK one! - I wonder how they deal with it ) - replicating any chassis no is also easy - see ebay UK etc etc - under 100 quid, 2 weeks and your new strut tower plate is waiting at the P.O.)
It may be upsetting for some - but it's certainly no secret.
An Aust del v6 is worth what it's worth - regardless of the tag - as long as it's a v6 one - a 4 cyl shell has to be significantly modified in order to fool a Capri nut - a lot of work fr little joy - but an rs3100 - with it's UK tag - esp at UK prices ....

be good if you could get some tags like the waterways ones they put on ya boat stamped with your chassis number and hide a few in some places  during the resto take pics etc

My new ID plates arrived from the UK today - for the RS3100. Very neat and tidy. Look the part for any situation and do add a bit of tiny bling to the engine bay. U would be fooled by them. They are great but if you've seen a set of originals - u can pick them out - prob a good thing.
Now - if I see a set of ID plates on an RS (or facelift)  ill know straight up whether they are later copies or the real thing! It still wont stop me using these ones  - but ill keep to old ones nice and safe .... (they are also approx. 1ml wider and longer). (of course the Aust ID plate is a bit of a clincher for our RS's)

I have to say Spud that owning the Perana you can get reproduction plates for that. I reckon you stick with the real thing and that if you do, it will be more worthwhile. I bought some of the repro plates for the Perana but their for a cabinet not for your car. Or their for your car so as the real plates always stay with you. I Don't know best way, really as the RS is an expensive car. Same prob i have with the Perana should I remove the original plates for safe keeping, then replace or always have the chance the car is lost, if its stolen. Keith

yep - if I don't fit the originals - ill tape them up behind the dash
