The George Beale replicas would almost certainly be eligible and I'm quite sure that the noise wouldn't be an issue if the DED decided they wanted it to happen. I suspect the biggest stumbling block would be that they were £250000 to buy and probably haven't lost any of that value since. That's a lot of cash to risk on someone chucking it up the road or blowing the engine to bits (actually Hondas don't do that apparently, so it would be an 'electrical failure')
