I got mine done at 50k miles, so IF it was done at 60k miles then i would do at 110k miles, it is such a critical item (new engine if it fails) then why take the risk?
Phone around different dealers, I got mine with pump and rollers done for £350 but was quoted £330 without pump at same garage at a different dealer £300 for no pump and £399 incl of pump, all at main dealers, actually both garages owned by inchcape and within 30 miles of each other!!! the £350 incl pump garage actually only charged me £340 "we did it a bit quicker than we thought Sir" how good was that :) never had that before.
