Comfort and Convenience
Seat firmness is largely personal. A firmer cushion suits drivers who like a settled, supported feel, while others prefer softer padding; the same seat can therefore be judged very differently.
Safety and Driver Assistance
Spending a few minutes with the controls while parked helps you locate wipers, lights and demisting without searching for them later. Layouts differ between cars, so a short look through the handbook is worthwhile.
Multimedia and Connectivity
Charging, calls and music are separate needs. A cable may power a phone without carrying audio, and where hands-free calling is available it generally pauses playback for the duration of the call.
