Nice ride, lot of goodies?
I was in an S several times and was quite impressed, deceptively fast and for me almost too quiet. like have to use the cruise around town quiet. I found myself at 60 when I was thinking 35 several times
I know you want to keep it nice and not treat it like an appliance, but you do have to sacrifice to have great cosmetics. Either find a detail shop that will wash de-tar, clean, polish, glaze, and wax the piss out of it a couple of times a year or learn to do it yourself.
Washing it by hand is one of those sacrifices I choose to make but you can make it look "client" nice by blowing the crud off. Green Lantern is worth checking out. or hitting the hand wash.
Srvy and I agree wiping it down after a less than thorough wash is more damaging than leaving the film.
Good luck, May I suggest you look at buying a random foam applicator and start reading up on what to do and what supplies you will need. Or just drop a few hundred at the detailing shop and wash it however. I got one for a runabout and started using it to apply glaze and wax. Really works well, light.
Here's some reading material....

Gary Dean , I think he used to e a State Fair "barker" I'm still not a fan of rinse less washing but it does make sense...
