Comfort and Convenience
Seating position is personal: height, reach and how upright someone likes to sit vary with build and habit. Two people sharing a car on the same route will often settle on quite different arrangements.
Safety and Driver Assistance
Time spent in the car park learning where the lights, wipers and mirror adjusters sit is rarely wasted. Sorting mirrors, seat and settings before moving means fewer fiddly changes once the road demands attention.
Multimedia and Connectivity
Phones drain quickly when navigation runs all day, so a charging point within reach is worth checking for. Separately, whether calls and music can be handled without picking the phone up depends on how it is connected.
