I've got 4 Vehicles currently, all have pp's bought from DVLA, all are relevant to the specific vehicles and / or to Mel & I, my customers, friends and family all "get them" without having to ask ..................
Not one of them cost more than £300 inc transfer, and the 2 restored Cars that are in my MB Collection are same series.
If I buy a Sales Car / Chopper in with a cheapo pp on it I leave it on, unless the PO wants it back, in which case he pays the fee, or if it's left on the car it will get sold with the car
I am yet to get one like D1 etc left on a vehicle, but of course if someone was that stupid, yeah I'd get it on retention and auction it off, course I would
I find a lot of these cheap meaningless Irish etc plates are put on some old tat Car by the Champagne Ideas / Lemonade Money brigade, then they tell all their neighbours etc "its a 2015 Discovery yak yak yak" or whatever.................
"Errrrrrrm, hey twat" Land Rover stopped making that model in 2009 .....................
