As I suspected, it looks as though the changes to this car have not been reported to DVLA which still shows it as orange.

Quite how it will get an MoT now I don't know. Any application to register it as MoT exempt due to age will I think neceesarily require an untrue declaration as to condition, and as soon as any modifcation is declared then Q-plate looms, and once you get a Q plate there is no escape ever from tax and MoT (I have two such cars, and believe me I've looked at this in some detail !). Of course, failure to declare and untrue declarations will also invalidate insurance.
