Comfort and Convenience
Temperature is a good example: one person wants steady warmth while another prefers cooler air, and the same setting rarely suits everyone travelling together. Height, clothing and where you sit all change the impression.
Safety and Driver Assistance
Before a first long drive, it is worth spending a few unhurried minutes finding the lights, wipers, mirrors and hazard switch while parked. Looking for them later, in traffic or rain, is far less comfortable.
Multimedia and Connectivity
Keeping a phone charged on a long day matters most if you rely on it for navigation; a flat battery ends that quickly. Where charging is available and how it is arranged is worth checking.
