2007 Mazda MAZDASPEED MAZDA6 Sport 4dr Sport Sedan AWD (2.3L 4cyl Turbo 6M)
In 18000 miles now, I've been to the dealership 5 times, 4 for service, and once for a check engine light (put crappy gas in it), handles very well, a lot of fun in the rain/snow with traction controll off. Quick off the line. Not quite an STI in performance (heavier and less hp) but really comfortable and a lot nicer inside. Have no doubts about taking clients out in it.
Comfort, style, subtle styling (doesn't get stared at or pulled over often).
