I live in Oklahoma. I bought my Vanguard in 2003. I paid around $7600. (with the same cd ozone, lifter, starter chems, etc.
I only have 1 pump and I think the 2005 have 2 now. I have the regular moto-massage seats, which I believe they now have the dual moto-massage. There are some differences, but fwiw, I think your price seems about right!
P.S. I LOVE MY VANGUARD!!!
