Interior materials on the M2 are not as nice as the M3/4. Carpet pile is cheap feeling on the M2 and I don't even think you get a stitched sensatec dash as standard on the M2. Vernasca vs merino leather as mentioned. Door card injected moulding isn't as squishy and the texture isn't as nice. No ventilation option for the seats as mentioned. No rear zone climate control on the M2. Probably less sound insulation as well (M2 road noise is more noticeable).
