My tuppence worth........(which doesnt go far nowadays....!)
If you have an MV that is obviously "What it is" not a problem, ie; Armoured Car, Tank, Carrier etc.
If you have a vehicle that also had a civvie version, Truck, Bike etc then its easy to bring some form of ID on it as most of have history on their machines! Its what we do, get the vehicle, restore the vehicle and search the history of the vehicle.
Theres the other side of it tho, the ones that have built their own from another vehicle because either they cant find one or the cost of owning the real one such as the Private Ryan Tiger (Plywood???), RAF Armoured Car (From an LDV chassis I think!) etc. These are obvious tho, even to the uninformed, so i dont have a problem with these.
I agree tho, getting the Ford Mondeo, taking your Tesco shop out of the boot and putting UN in black electric tape down the sides (or eben MP!! to get into a show is taking the p*ss!!!:shocked:
Dont shoot me down, just an opinion that i have and makes sense to someone else prob, but many many miles away I guess!!!!:undecided:
