When I was selling cars in the early 80's the 'special edition' was a regular thing.
A stripe, different hub caps, a near side wing mirror, we'd come up with (silly) names and one would get chosen, it would go in the local paper and we'd wait for the weekend rush.......
It was only a few quids worth of bits but it was amazing how folk went for it.
I always thought it was a shame that MMC felt they had to go down the special edition route when they have/had such a unique product.
