Loved my 2003 540i. Got it with every option including the M trim package. Even had a different rear differential that could light up tires whenever you wanted. Put it on Autotrader for what I thought was a fair price (basically what I bought if for one year ago) and it sold in one day. Own an E60 540i now, but still liked the size of the E39 until my kids got too big to sit in the back.
