Hey, Nathan here from Searchtempest.com. Thanks for the link! Just thought I'd mention there's a small problem with the way the keywords are entered in your search. You've got (ls400|ls 400), which translates to "ls400 OR ls, AND 400". What you want is "ls 400"|ls400. The quotes mark "ls 400" as a complete phrase. This search should give you what you want:
Searchtempest LS400 search
Cheers,
Nathan
