I wouldn't worry if I were you. The last few times I've been on the loco hauled sets, the seats have beven worn out. Travelling with a spring sticking up your jacksie takes the shine off the experience; the carriages either need a refurb or scrapping. 168s are more comfortable.
Never had that experience thankfully on the MK3s, and 168s are definitely not more comfortable. They make a LM 170 feel comfortable...
