Hi! I am a potential BMW buyer!

I have my eyes set on two cars:

2007 328xi
$18,495
-90,000 miles
-clean CARFAX 1-owner
-White ext.
-Cream int.


2006 330xi
$19,995
-47,000 miles
-clean CARFAX 1-owner
-Gray ext.
-Black int.


Thoughts:
My price range is supposed to be under $18k, so I would prefer the 328. I prefer the exterior color and interior of the 328, but the seriously high mileage scares me. The 330's additional power is much more tantalizing to me, but it's a little out of my price range, but I still like it (the interior, not so much).

What I need help with:
-I need you BMW nuts to help me negotiate what is the best offer or deal that I can get for these cars
-Which car would YOU choose and why and
-Any pros or cons that would help you make such a decision


Thanks and I love the site,
