Wasn't looking for actual numbers, just a rough idea, if that makes sense.
I can find a brochure for it in the Document Archive, which is actually how I know about it -- if the Archives are complete (I assume so, but you folks are the experts -- you tell me), then they only made it for the one year. It was a thirty-foot model, and from the literature, it sounds like it was a modification of the 30ft Liner model that year.
Direct PDF link to the relevant brochure in the Archives.
My guess is that it didn't sell well... they would've likely continued it, if it had.
FWIW, there's thirteen classifieds that fit the decade, at that Classifieds site you linked to -- and none of them are a Salon Liner. I've mostly been perusing Craigslist lately... there's a few in my area (the Raleigh, NC CraigsList serves me). I'm somewhat limited because I have so far chosen not to learn to drive (trust me when I tell you that we are all safer with me as a passenger), and I'm on Disability (mental stuff, actually, more than physical) so I'm bloody poor. As far as tools go, I'm decent with hand tools, but don't ask me for power anything unless it's a drill
I can't even jigsaw. I have one (a 90s era B&D, I think, might be a Skil, I'm not inclined to look right now) but the blade falls out every inch-and-a-half or so, when I try to use it. Might be it, might be me.
