The irony is that by doing those mods he's detracted from the value of a real limited edition Anniversary model which he is at pains to point out in the listing.
Any value enhancement of it being an Anniversary model would be instantly wiped out two-fold because of the mods.
As i'm sure you know Alan, many manufacturers made limited edition models, mainly to boost sales of run-out models. With this being a 1977 car, it is to commemorate the 50th Anniversary of Volvo who started in 1927 as a spin-off (yes, pun intended!
) from the Swedish Bearing Factory or as we know them, SKF (those being the initials for the Swedish words for Swedish Bearing Factory) so is a genuine limited edition, not a marketing idea to shift otherwise redundant bodyshells!
