There are getting to be many Lexus/Soarer/SC-400 web sites available, these cars truly have a cult following.
The ones I use most frequently for good information are:
Soarer Central The worlds biggest forum and resource for Soarer owners
ALSC Australian Lexus Soarer Club
TIF Toyota Imports Forum (British)
LSOC Lexus Soarers Owners Club (UK - revamped)
Club Lexus (American)
Planet Soarer Everything except a forum
