From what I've read, other than the timing belt, there are tons of cases of the ZF transmissions on the D2 A8/S8 cars going bad. The S8 IS a different transmission from the A8, shorter gears, but I've been reading that if the transmission still works well at ~100k miles don't touch it (aka do not attempt to drain and clean the transmission fluid etc) but if there are issues apparently draining and pulling all the gunk out could be a solution.
I played around with some of the electronics, heated seats, rear sun shade, headlamp power washers, trunk/gas release buttons, etc. I didn't completely look into the auto-leveling headlamps, windshield and sideview mirror defrosters, or ALL the switches on the dash. I will be sure to be very thorough should I take a look at it again.
The D2 is a great car from what I've heard, and I'm sure the S8 ices the cake. Just remember that actually working on a relatively modern car, especially a German luxury car, is a lot harder than what many of us did as kids with our parent's cars. You can't just replace a lighting or mirror module if it's faulty. You have to replace it, then code it. That coding might or might not be tricky and at the least, you're buying the module, the cable and spending a few hours on the internet trying to figure out how to do it. That's a very simple electronics example. It can get easily out of hand when you're getting into things that are cheap part cost wise but expensive electrically like valve timing solenoids.
I'm a BMW guy, but even then I'd really hesitate to get one out of warranty unless it was fairly historically significant like an E30 M3 or 2002.
