The document as you say does not have a place for construction & as you said the DVLA site does, it quotes manufacture as 1984.
I am looking to get it changed to historic tax class.
When I brought the car out of my father's garage I also found two carrier bags full of cassettes, mind you I'm not sure I can bring myself to listen to Nana Mouskouri or Demis Roussos.
Thanks Huw, I've checked out that website & I think I'm going to go down that route. Period looks & up to date sound & quality sounds good, I will let you know how I get on.
Yes that makes sense, well it's been there that long I'm just going to leave it that way but I am going to have to change the speakers as they. Sound really bad.
