A value comparison 1999 vs 2019, D2

[Regulus]

I came about a Swedish article on the A8/S8 written in 1999.
https://teknikensvarld.se/provkornin...uattro-122908/

It mentions that the S8 cost SEK 750.000 new in 1999.
Dividing that sum with 20 years, equal SEK 37.500 a year.
So far, the D2 S8s on the Swedish market span the range of 1 to 3 times the year value (37.500).

In other words, I could buy 7-20 cars today, for the money that the new car demanded 20 years ago (if I had that kind of money)

How does the British market compare?
