Looks good to me but the price is really high - you should be able to pick up a 2006 or 2007 for the same price or less. However, if you're looking for a manual car they are definitely more difficult to find.

Here are some examples:
BMW : X3 X3 4dr AWD 3 BMW : X3 X3 4dr AWD 3 | eBay
BMW : X3 3.0si CPO BMW : X3 3.0si CPO | eBay
BMW : X3 3.0i BMW : X3 3.0i | eBay
BMW : X3 BMW : X3 | eBay

I imagine the heated steering wheel and seats are a must in Minnesota - my wife can't live without them!
