The interior layout, fit and finish
Finding a driving position that suits you is very easy because you get lots of adjustment in the seat and steering column. The two seats are very supportive, even under hard cornering, and are comfortable for long-distance drives, too. In front of you is a configurable TFT display that replaces conventional dials. This proves clear to read and easy on the eye.
From the driver’s seat it's relatively easy to see forwards out of the 540C. Reversing is a bit tricky, though, so you might want to add rear parking sensors and a rear-view camera, both of which feature on its extensive options list.
