2006 Ford Mustang GT Premium 2dr Coupe (4.6L 8cyl 5M)
I'll be sad to see mine go. I've had BMW's, Camaro's, and Vettes, and this is by far my favorite car to date. Very reliable so far with only one problem (fuel gauge sensor) but otherwise a perfect all around car. Not too fast (yes there is such a thing), but more than fast enough to get you in trouble on any road.
V8 sound. Best exhaust note ever.
Interior material quality. The 06 didn't have heated leather, but they fixed that in 07. Also a bit more exhaust note would be awesome.
