It’s only since the mk7 that the performance Golfs had increasingly loaded standard spec as each year went by.
Even as recently as mk5 and mk6 the GTI came with a fairly basic spec, no DAB, no nav, no xenons, 17” wheels etc etc.
VW had to compete with the likes of Ford and Vauxhall who had more powerful hatches with better spec for less money so changed things around in the UK, Irish specs are probably different.
The mk7 became a bit of a Goldilocks car but ironically the pre mk7 models depreciated less drastically (ignoring current worldwide market weirdness) however VW seem to have taken the lion’s share of the hot hatch market sales now.
