I was able to get mine down to about $7800 including an upgrade on the cover lifter, but at that point I started meeting strong price resistance. Bay Area, CA prices (where everything is inflated) might apply. You would think TX prices would not be as high, so I agree 8700 sounds like the "sticker price" and I'd push back a bit.
John, thanks again. Just made a deal on a new caspian for around what you paid. Should have it in about 4 weeks. We're pretty excited, actually like the Caspian better than the slightly larger D1 and Sundance that we tested. Also thanks too the folks that mentioned possible sales tax rebates. I've been seeing a chiropractor for my back, and apparently if I get a letter from her that the spa would be therapuetic, TX will rebate back my sales tax, a not insignificant savings.
