I really like this model. I'm looking for a primary A to B vehicle. I already have a 2006 Mazda 6 that is paid off. I would like to know if this BMW is a good deal.

Also, there is 43500 mi already on it, but the warranty runs out at 50K or until 2011. Will I be able to extend the warranty? Or will I be stuck with expensive mechanic bills if something goes wrong?
