I traded in a Audi A4 for the IS250 and have been quite disappointed. The transmission is rough when shifting, it has no get up and go, and the blind spots are huge. I find myself having to look around a lot more in this car and am way more cautious after several near collisions because of the blind spots. The Audi was fun to drive. The IS250 is a chore. I'm getting rid of it after only 1 year.
