Now with the new E70 price released, anyone can comment the current E53's value drop? I am asking this because I am in the market for a 2004 or newer E54 4.4. but I saw saw the E70's 4.8 price, I am thinking maybe I should wait a bit longer or just get a brand new RX350 instead. (currently, a loaded 2004 X5 price almost identical to a loaded brand New RX350 price)
