 I had this 2004 Z4 3.0 for the last 4 years. Silver titanium. It is impressive, I love it very much. Drove it all year around in Detroit and Minneapolis. This car is great on snow with the right tires. It is fun to drive. I test drove the SL55 AMG as my next car possibly. Let me tell you, I have  to think twice now. Z4 is even more than what we may think. It has been difficult to choose something else after you drive this car. Most likely it will be SL55 AMG though for me tough decision to move from the Z4 even after more than 4 years driving it all year around. Never drove a car for that long. Go get one don't even think twice about Z4. :)
