While the steering wheel has a decent amount of adjustment for both reach and height, adjusting the driver's seat is rather less straightforward. For example, you have to pull a lever and shift your weight around to change the seat height or the angle of the backrest, although there is at least a good range of movement. Paying extra for electric seats is an expensive way to get around this problem.
The driver's seat is generally comfortable and supportive, no matter which version you go for. However, it's a shame BMW charges extra for adjustable lumbar support, which gives better lower back support on longer journeys.
The dashboard controls are nicely positioned within easy reach of the driver, including the climate controls, which are also easy to use.
