The only car I approve of them making it is the BMW 530d. It's a brand new car (BMW 5 series sedans as police cars are nothing new, but the 2010+ model is interesting. They're not even used that frequently as police cars). They shouldn't have made the 330d police car; better to wait until 2012/2013 until the next gen BMW 3 series comes out, then use that as a police car.
