Sorry if the truth hurts, but there are plenty of other brands out there that are as good if not better than Alfa.
Without wishing to get into a slanging match, that's only the truth from your perspective.
I'm not a die-hard Alfa fan. In fact, the Brera is the first Alfa I have spent any serious money on (previously had a 166 for about a year). Other than that, my own cars and the cars my wife has driven have included lots of VAG models, plus our latest Volvo C30 R-Design, a couple of Peugeots and Saabs.
The VW products were (largely) reliable and pleasant(ish), but the Brera has been reliable, very pleasant and looks fantastic.
My own experience of German cars is that everything people rate about them only works if you "buy" it. I found all our VAG cars to be over sprung and nose-heavy, never a pleasure to drive and I've not missed a single minute with the Audis, which were atrocious to look at, to drive and to own. The VAG dealers were more than capable of being frustrating, rude and inneffective and the Audis spent a lot of time with them, compounding the issue.
I'm absolutely with you that plenty of brands are as "good" as Alfa, but, coming as I am from the other direction, it's an absolute pleasure to be out of VAG and into something different. Are there better handling cars? Sure. Are there faster cars? Yep. More efficient? Check. None of this matters - been there, done it, and was bored within hours.
Personally, I am glad that you are having such a good time in the VW. Sounds like you had a bad time with Alfa and that's a shame. But the "truth" is only as each person sees it, and Alfa make some great "feel good" cars which look like nothing else out there and offer an alternative to the extremely predictable suspects, however good they may be.
It's also worth remembering that the Brera is now a few years old. It's not surprising that the very latest model from VAG can match or better it.
Live and let live, and enjoy the VW.
