Interior upgrade

[KPlanting04]

Hey, i already have a Vectra A 4x4 Turbo, but i wanted a more modern car and i fell in love with the Calibra. so i was thinking about a fun project where i was thinking of rebuilding it more modern. New suspensions, better servo, modern functions (cruise, heated steering wheels and other modern stuff). But i was wondering if anyone ever have done this? I am in love with the Mercedes W204 Gacelift interior, but i guess that is a much bigger interior. I have also seen the suicide Vectra with Audi tt dashboard so that could work too. Any ideas? I was thinking dashbord, doorPanels, middle console could be the most difficult Mods to fit.
