I have just bought a Disco 2 commercial and am about to fit rear seats to convert it to a car. Does anyone have any thoughts about how easy or difficult it is to change the tax class from LGV to PLG. I have had conflicting advice - The DVLA's helpline told me it was not possible at all but the Post Office website appears to suggest that it can be done as long as "supporting evidence" is provided. I presume thats means photographs of the fitted seats and seatbelts etc. Anyone done it?
