When you look at the prices of the Caddy and the RC, be sure to factor in the very rapid depreciation of the Caddy. I have friends who lost 50% of the value of their Caddy in 2 years (or, as one said, "I got hosed on the trade-in.") Lexus retains more of its value over the years than almost any other car on the road, and that's an element of its cost that many people don't consider. I just traded in a 2002 SC for almost 33% of its new car cost, and with patience, I could probably gotten a little more in a private sale, but convertibles are a hard sell in December.
