You could always move to the states if you want that sort of thing.
Because that was the format when that plate was issued. Iirc the first plate issued in the uk was A1
You could probably get T13 VOM but I expect that to be taken already and yup, just checked, it belongs to a Volvo C70 T5.
I understand private plates to an extent - in that they make it look marginally smarter (shorter ones anyway) and hide the age.
