TBH Donalh...I think you're better off without the "excess fat"; I know people love "toys" in their cars but....cars are made to be driven, especially something like the Giulia. So, stuff that influences the dynamics is very welcome - the paddle shifters on the steering column for example make the fact the car is auto bearable and even enjoyable with a sporty, single seater like feel (although I don't understand the fad of having them bolted to the column); The active suspension - great to have, but might be extremely expensive when it's time to change the shocks.
The price of the "winter" and "sound theater" packs, together, is that of a decent second hand car...for what are, in the end, useless gimmicks: the heated seats, maybe they have some use in Siberia (and even there, I'm sure I'd be sweating on them); Folding mirrors, I have hands perfectly capable of doing so; Don't even get me started on the electric/power seats, a pointless complication of what is a very simple, yet effective adjustment system; And all the sound stuff...I won't be paying enough attention to the music (or better, shouldn't!) to notice the difference between a 200 Euro set of decent speakers and a super-hyper-ultra-clear-mega-hd-super-definition one, with traffic, engine and road noise in the background.
As for the "passenger's comfort and entertainment"...they got plenty of views outside the windows, for free!
