Judging by the number of naked front plated cars (Ferraris, Lambos and souped up Audis and BMWs mostly) around here I'd be amazed if a 7 was done for it. But that's round here, other areas may vary. I wouldn't be comfortable driving with no plate on the front, but would consider a stick on one. I too feel a full sized pate looks big on a 7. I found a 5 digit plate and got them made up full size, but for 5 digit size, so not as long. These are legal* . You can even justify the expense with man maths as they save weight and possibly more aero...(!). DVLA direct is a good place to seek out C7 xxx plate or similar at a good price. *technically my plates aren't legal as they don't have the post code of the manufacturer on them, but they are raised letter style not flat perspex and are the legal style of what was available at the time the car was made. I do know hey are recognised by cameras as I've be charged by Dartford Crosding. m'lud.
