2007 BMW M5 4dr Sedan (5.0L 10cyl 7AM)
Probably the only car you can store your golf clubs (it comes with an illustration for 4 bags), bag cart or baby stroller at the same time. Great amenities such as window shades, adaptive headlights, etc. Five people fit nicely although the rear folks will be crowded. Nice exhaust note, lines. Gas mileage and transmission is another story.
Sportiness meets utility. Inconspicuous, high performance sports car. Techie features (bluetooth, iPod connector, heads up, iDrive).
Gas mileage: 11.8 MPG? The iPod interface is difficult to navigate to a specific song or artist if you have many stored. The GPS nav is extremely slow - maybe it's normal in other cars, but I counted 4 seconds load/refresh time of streets, etc.
