The IS and the BMW are both great cars. I have a '00 328ci and bought a '02 IS last week. The IS is more every day fun, tossable and sporty. The BMW just cruses like few other cars. It inspires confidence with stablity. It is great in corners, but it just feels a little disconected from the road compared to the IS. I wish I could combine the two. That would be an awsome car.
