Well I feel like the ultimate idiot, although its not really my fault. I got the # of the guy my friend is hooking me up with for the sale and it's a actually an E53. '06 that he didn't specifically state the names of options but has a trailer tow on it, DVD, it's the 3.0 not 4.8 and seems to have everything but a nav system. Seems odd that it doesn't. Was that pretty standard? Anyhow he's also selling a house so I may not get to look at it til next week.
