Big woo hoo! Just received word back from the DVLA. They're happy with the car! They may want to see the chassis plate installed and have a copy of the chassis receipt but overall they're happy :-)))
That means I can go ahead and get the VIN plate made and get my ar$e in gear to get the car ready for an MOT. All I need now is to get the V5 back and I'll be really happy.
