How Many Miles Do You Have?

Have 2019 corola hatchback. hope new drive train dose as good as in past models . its got 800 miles so fare.
I like the hatchback but I got such a good deal on the LE Sedan at the end of year I am pretty satisfied. Actually my son will get it when he goes off to college and I will be back to my old 03 Honda Odyssey beater.
I have a 2010 le with 122,000 miles, I would love to get to 300k with the original powertrain. I do all my own mantainence and repairs. I’ve only had to do mataience. Just put in new plugs at 120k. I am about to put new rotors and pads on along with flush the master cylinder and lines with fresh fluid. I am just going off best judgement after superpassing the manuals last service interval. I would love for advice or tips. It has a 1.8 L.
