G'day mate.
My '07 Lumina has just under 150,000. I bought it with 110,000 on it and I have had no issues with mine.
It's been happily running on LPG since 125,000.
Make sure it isnt sludged for a start.

My boses ve sv6 just clocked 220,000 and well to be honest its been flogged it's whole life. Had no issues with it whatsoever
Mine has clocked over 160 and has no issues. If anything a slight rattle / knock on cold startup. After you check the oil listen closely to the engine when you start it up ... for things like timing chains and big ends, but again thats obvious. Most of all check the log book and service records.
Look into the engine at the oil cap and remove the filter and check for thick sludge. When you open the cap there should be a shiny metal plate in there not brown sludge.

how are alloy tech with oil leaks ? ecotecs were shocking...leaked on every possible basket ?
with those K's I hope you're getting a good deal!
220,000 km on mine - had to replace the throttle body (~$400), but apart from that, all OK. Check for regular service intervals, and see how it drives. You should get it pretty cheap with those Kays.
guessing it was an omega? not in your state but cheaper than the one you were looking at with almost half the k's Find Cheap Used & Second Hand Cars For Sale | Willaston | Gumtree Classifieds
You never said if it was a SIDI or alloytech. If it was alloytech then 16K isn't a good price for those K's in my opinion. SIDI on the other hand would have been an OK price. Also with high K's, it's not just the motor to worry about, the rest of the car will also suffer.
timing chains get "NOISEY" on start up when the guide wears out / jams up
