2004 330i performance package prices?

What is a good price for a 2004 330i with performance package, automatic, leather seats, moon roof? In Corpus Christi, Texas they are running about $45,000.00. What is a good price for this set up? I don't want to get ripped off. They really push the lease....but I dont want to lease a car for 600 - 700 dollars just to turn it in. This ais a Great deal for people that want a new car every year or so.
