Well that's good to hear. Plus I like the idea mentioned regarding changing all the fluids, not only are you teaching, you also get some bonding time. Lots of bonding time changing trans fluid on a NAG-1 trans, as I suspect it's equipped with. You will need a special cable type dipstick, available on Amazon or eBay. Get a name brand one, such as Dorman, because it comes with a temp/fluid level chart. Also some Torx bit sockets. Quite the task, and you will wear some trans fluid in your hair. It's a messy job even on a lift.
Check the valve body harness plug on the passenger side of the transmission for leaks, likely it has had the updated cup plug adaptor installed by now, but if not it's probably leaking. The original had an opaque/whitish o-ring, the updated plug adapter has a black o-ring. If it's not leaking leave it alone.
The rear axle shaft seals are known to leak at the rearend housing, pretty intense job. You must remove the differential to replace them, and must twist it just right to get it out with the axles still in place. Trust me, it's easier to remove the differential than to remove the axles.
Maybe check the front suspension tension rod ball joints for wear and play, very common wear item. These are the arms that go from the steering knuckles towards the core support.
Enjoy the car and hopefully all goes well.
