hi its a very grey area and a lot as changed over the years, i would say if its the right money buy it and you can get a better idea when you start digging into it more. at the end of the day if it had id he would be looking at double the price it is now or even more. i had a 3dr cos shell on a q and i was not sure either but if you ask the right questions to the right people in the right places you will find an id, i was offered an e plate id for £500 or look for a rotten shell sometime along the way, its to solid to turn that down, if it had id and rotten would you buy it then? something will come up other than a q plate, do a resto thread and people will help you on here, classic movie quote IF YOU BILD IT, ID WILL COME lol good luck.
