I understand, Kevin. I gave up my beloved C-Class two years ago to buy the X5. I love the X, don't get me wrong, but I LOVED that car. I was so sad, I would not drive it to CarMaxx (wife did), and after I signed the paperwork, I turned around and would not look at it. (a little pathetic, I know.)
Anyway, sounds as though your future wife is perfect for you - in that she understand your passion for cars. I'm sure you'll have a turbo e90 before you know it.
