I called the factory recently and asked them how many Plus 8 cars they had built since 1968. Of course, with nothing on computer, they didn't know. So my best guess is that they built approx 3 a week on average... 50 working weeks a year.. that is 150 a year... for 36 years.. is 5400.
Anyone have better theory or facts?
If we say 4 a week its 7200 cars but I don't think it was more than that.
