2006 Ford Mustang V6 Standard 2dr Coupe (4.0L 6cyl 5M)
So far I have only 325 miles on the odometer and the car is still under the break-in period. There are few major changes from the '05 model. But my car has two: the new tungsten grey paint and the 18" wheels. Both are a wonderful addition. Overall, the car feels solid and rattle-free over bumps. The new 18" wheels and slightly adjusted suspension do a reasonable job of dealing with roadway ruts and potholes. The new grey paint is metallic and highly reflective. The exhaust note is worth the entire price of admission. The 5 speed manual is a joy to shift and is the best manual I've ever owned or used. Rear seat is fairly cramped, but I expected worse.
Engine, exhaust note, red leather int, 18" wheels, tungsten paint.
Light around ignition key insert. Get rid of slight rattle from clutch plate. Some interior trim on the cheap side.
