First - Congrats on making it here. Lots of real BMW evangalits found here and many who can offer help and advice on just about anything and everything that could come up.... so, welcome.

Nice purchase.

In terms of the resale value of the 3.0 v 4.8, clearly the 3.0 will hold its value more IN THIS MARKET. First of all, you have a declining economy, so people want to spend less - which makes getting into an lower cost BMW more attractive, second, as a result of this economy, the gas prices have skyrocketed and getting 12-13mpg in the X5 and putting in $4.50+ gas twice a week (depending on how you drive/commutte) can scare the hell out of people. I just sold an Audi S6 - a v10 - it was selling bags of sand in Miami.

One cool mod, electronic, not performance is the DVD. Check out the other thread in the formum called, "DVD in motion.." i talked about what I did to my DVD player in the car - very cool.

Anyway, congrats and welcome!
