Heh, welcome to the fabric roof owners club!
Mine too has the same roof, black tho... with an aftermarket moon roof.
I too have been wondering as to how it was done...
Surprisngly the top has fared well... shes an '89 bought from Florida in '98, and been in NY until '06 when it was brought back to FL and now I've got her...
so 9 years of snow/ice.... its still in near perfect condition, but the top has faded... but I've heard of a cloth roof rejuvenator that someone posted in the detailing section (that I can't seem to find) its like a paint, and it just brings it right back to life.
As to care for it? I dunno, I guess just avoid the sun as much as possible.... mines had probably one of the harshest lives, but its still here to tell the story... so if yours is kept in good shape you should be fine
Any car that could survive my mom for 9 years while being a daily driver in New York, when it was already 9 years old, and is still around to tell its tale, is one TUFF car!
The wrap around chrome stuff... it was loose, so I took it off, breaking more palstic clips... well, I've replaced them all with good clips... and now that trim just dosn't want to stick to the clips and to the car... its quite a pain int he butt...
