Nice, but what about for the Euro 5 style? Like changing Express
502 or 506 to 518, then replacing it on a BNDEP euro v or changing
the rego to a BNDEP euro v rego.
Wanna have a sneak preview of it. 
maybe we could try using like this for the EDS:
'EXPRESS' from either 502 or 506,
'5' from 502/506/52,
'1' from 143
'8' from 88/78
