[Shotimes] Leather Conditioner / Repair AND Gen III mirrors?

[Chris "Zap"]

As the clutch progresses along, I have a few other issues to deal with on my
SHO (and my Dad's '98 SE).

I have looked around to find the recommended leather conditioner listed on
SHOTimes, but no such luck.  What easily available leather conditioner works
well on the SHO full-leather seats?  My driver seat needs serious attention,
due to a spreading crack :(  Also, has anyone patched such cracks with a kit
or other type of method?  Is it easier to replace the panel?  I would like
my seats to stay in nice shape, but unfortunately lack of past care is what
got them into this shape.  I tried conditioning the seats once since I've
had the car, but I'm not sure that it helped.  Any advice is appreciated, as
I am willing to care for the leather if it will do any good from this point
on.

Secondly, my Dad's '98 SE (Toreador Red) has had its passenger side mirror
damaged.  I was curious if anyone knew how to tell the difference between
heated and non-heated mirrors.  Also, while I'm at it, if anyone has a lead
on a Toreador Red passenger-side mirror it would be appreciated.

Thanks,
Chris
