Yes I have been seeing prices coming down for a few months now.
so I don't mean for this to talk you out of buying it. but just stuff I would have liked to have known before buying mine. well, OK I mostly knew but bought it anyways haha. which you very well might too.
so afm. it's a mechanical failure of the lifters, but there's 3 different reasons they can fail. first lack of oil changes, the wear internally or build up gunk and get stuck. but they can also fail because of a electrical issue with the vlom or a lack of correct oil pressure, either from a bypass going bad, or one of that gaskets under the vlom. the bolts for that cover are commonly found finger tight.
so basically it depends on how they "fixed' the lifter failure. I of times just dropping in new lifters fail again in less than the time the first set failed. the only 2 correct ways is to replace everything involved with the afm, from top to bottom or a complete delete, all hardware and relash the ecm. both of which I have doubts the dealership did or even will do.
the motor mounts being changed is nice, but if they used oem, which they probably did being a dealer. they will rip again in between 40k to 80k as my guess. the real fix is ones from a H3 hummer or aftermarket poly mounts. any other replacement fails again again.
yours 127k is pushing the time is ready for a new torque converter before it releases all its metal and takes a $7k tranny with it. while there, soon the oil starts leaking around this mileage. so factor in oil pan gasket, rear cover and main seal, toss in the pick up o ring while there. but make sure you get the right o ring. the wrong one seems to be used often.
that's just what I've gathered from research. others might come and tell you have a good chance it's solid till 300k. but if I don't tell you and you're posting about 10k in repairs 6 months from now, I'd feel bad reading it.
