That's a nice story, thanks for sharing. In our area, I think all the Lexus dealerships within 100 miles are owned by the same person / family.
I have bought two RX's used and they are great cars. The Lexus dealer here has always dropped their pants for me on CPO cars and undercut anything at Carmax by thousands, so a completely different experience than the OP. But maybe they overprice them to start with, but I don't think so. I shoot for and end up with one of the lowest prices ever reported on all those car sales web sites and thousands below the truecar.com website.
