Hey!
So you're still looking? I just saw the first post and this last one...
In my opinion and in your situation, I would definitely go for a Mitsubishi Lancer Evo. First of all, it's a Mitsubishi, so it's pretty much as reliable as it gets (as any other Japanese car make).
4WD, for your winter needs, almost 300 HP, so you can have some fun at the auto bahn if you want to, and with a fuel efficiency hard to beat (for similar power cars).
After that one, I would maybe go for the Nissan 370Z. Similar in almost everything, except it doesn't have 4WD. Oh and it's a two-seater... if that's a factor.
I hate it when cars break down on me and need to stay in the shop. If you share this sentiment, I would avoid German car makes if I were you... 
Good luck!
Best,
Bruno
