I use my Z4 as my daily driver. After over 300,000 miles in Jeep Grand Cherokees and a Chevy Suburban, I had almost forgotten how much fun driving could be. I am surprised how comfortable the car is on a variety of surfaces - not harsh like a Porsche. Though the trunk is not cavernous, there is enough luggage space for a couple on a weekend getaway, and more than enough for me when I travel alone. Thought some would disagree, I find the styling to be unique, very attractive and quite modern. All in all, I am most satisfied with this car and suspect I will keep it for some time. By the way, 26 mpg city and 36 mpg highway is not bad either.
