About comfortability i think i have nothing to moan about my 406, only thing i perhaps dont like is that the gear box feels "tough" sometimes you think oyuve sifted the gear but you actually has not and must "re-introduce" it, appart from that i think i like the car in all its terms, light turn on automatically which is comfortable, and the same for windscreen wipers, they automatically turn on when water drops start falling on the windscreen, about the rest of the interior i find it well designed, well one very small id like it to have and it does not, the possibility of lifting up the driver seat.
