Newby here....

Looking at perhaps replacing our car w/ a 05 X5 3.0i w/ Sport Package and 30,000 miles on it.

How does the 3.0 do w/ the larger body of the X5? I know it does pretty good w/ the smaller X3. I do a lot of highway miles here in UT (75-80mph) and have a few Mtn passes to deal with on a pretty regular basis and don't want the engine wound out all the time - I won't have a chance to take one for a test drive for another week or so.

I would like the 4.4 but most of the ones locally have similar miles but a going for a bunch more $$.

Thanks for your input
