The 2009 BMW 128i is an amazing car in just about every way.
The strengths of the car include: great power and pick up, handles exceptionally well, little road noise, combination of sports car power and fun with touring car comfort that is unrivalled by any carmaker; this is, of course, BMW's bread and butter, excellent stereo system, great navigation system, including the ongoing display of necessary information (e.g. miles car will drive given the amount of gas in the tank), and excellent braking system.
The downside of this car: strange and almost useless cup holder; it is as unsightly as it is senseless, little room in the back seat (this is a sports coupe, afterall!), the inside doorhandles stick out too much; the driver side door handle hits my leg as I drive.
All in all, if you are looking for a great BMW sports coupe that rides comfortably and handles as well as any BMW 3 series, but manages to deliver all of this in a sporty coupe that looks a little different than the 3, this is your car!
