We have owned an SE since new, and it now has 134,+++ miles on it. We bot it to replace a Chevy Trailblzer with50k miles on it.
It has been an excellent vehicle. Aside from brakes and regular maintenance, just a couple minor repairs (gas door spring broke ~$100), VSC had to be reset ($45).
I changed the iridium plugs last fall in it myself, the 2nd set came out looking perfectly serviceable, and all were consistent in appeareance with clean, even fuel burning. No signs of oil at all. Like a new engine.
We run it on 87 octane, and nary a ping. A willing engine with plenty of torque and power. I think the tip-in on the accelerator is a bit much though.
I had the dealer change out the original tranny fluid at 100k miles per the manual (we don't tow). Still shifting along without issue. Had all the other fluids changed along the way as well.
BTW, this tranny has a real dipstick, so if you're into drains and refills, this is your machine. Later years eliminated the stick.
Our dino-only oil changes are every 5,000 (mostly highway) miles. Oil always drains partially clear. Filter at top of engine is a breeze. The foremost grease fitting is underneath an easily removeable plate, and should not be ignored at lube time. Six zerks, so don't skip any.
We get 22-23 USmpg summmer, just a tad less winter.
Frankly we've been quite pleased every mile. Built like a tank, we'd buy it all over again, it's been that good.
