The comment earlier in this thread regaring the larger screen is incorrect, FYI. All E60 5 series come with the idrive function; the only way you'll have the larger screen is if the car has BMW's navigation system. The NAV system gives the idrive a bigger screen, and force feedback through the round controller on the armrest. Although you're not likely to find an 06 around 30K, 04's and early 05's might be going for around that price range. Make sure the car does have a warranty when you purchase, and if it's a navigation equipped car, make sure it has the latest CIP installed, as well. Good luck.
