The mk4 interiors are looking a little tired ok, seats seem ready to be reupholstered, need new carpets and the return of curtains needed. There is cost cutting and then there is cutting off ones nose to spite ones face by aggravating some customers. But I find the mk4 sets the most comfortable on long trips, especially compared to the 'camber of torture' plastic seats on the 22k. I hope the mk4 sets are refurbished and not taken out of service on the Dublin-Cork route I regularly use. My bones wouldn't cope with a 22k all the way to the rebel city.
