Start with seat adjustment before judging cabin space

Cabin space is difficult to judge before the seat is set for the person using it. Begin with the manufacturer's adjustment instructions while the vehicle is safely parked.

Set the seat, steering wheel and mirrors as directed, then check that you can reach the controls comfortably and use the restraints correctly. Do not make driving adjustments on the move. If you are unsure about a suitable driving position or an adaptation, seek appropriate professional guidance.

Check the space you actually use

Notice the room around your knees, shoulders and head in that position. Include getting in and out: a spacious-looking cabin can have an awkward doorway. Avoid judging solely from a photograph taken with the front seat unusually far back or forward.

If another person will use the car, repeat the check for them and see how easy it is to return to each position. Check rear-seat space with the front seat set realistically, rather than optimising both measurements separately.

Record the exact model and seat configuration. Optional seats, roofs and trim can change the experience. The result is a practical note about a particular vehicle and user, not a universal claim that a cabin is roomy. Keep the final choice tied to the people and journeys it needs to accommodate.
