So how do I know if she's REALLY the right one for me?
Before I bought my M5, I test drove a 540 Sport 6 speed. I really considered buying that car, until the GF says: "you know you won't be happy if you don't buy the M5"
After I buy the M5, the GF and I go to the M5DE. On the first day, we drive to the Biltmore Estate in Z4 SMG's. While I might expect to hear "what a great drive, this is a neat little car"...what I hear is: "Why do we have to drive these whimpy little cars...why can't we spend two days on the track?"
One evening, we go to a company party. Since we are very careful about drinking and driving, she doesn't drink and is the "designated driver". On the way home, she asks: "do you mind if I open it up?" (the car had about 1,800 miles on it). I say: "Nope, go ahead". The next thing I know, we're doing 140.
Finally, since getting engaged, I sometimes feel like I need to be a bit more "sensetive" to spending money on mod's for the beast. Last month, I ordered the SuperSprint exhaust to add to my X-Pipe. I thought I had them shipped to my work, but they went to the house instead. I arrived home late that night, and found the box inside the front door. She was in the kitchen.

Her: "what's in the box?"
Me: uh oh..."That's some parts for the car"
Her: "what kind of parts?"
Me: "New Exhaust" *gulp* here it comes...
Her: "So, when do I get MY new exhaust?"
Yup. She's the one
