From the first test on the IS 250, I was sold on the silky tramsmission, fit and finish and quiet engine. I have had this car for less than a week and can not be more pleased. The power is a 204 HP so it is not going to jump off the line, but it is ample on the highway and remember it is that lowered HP that is more than making up at the pump. The rear seat is small, everyone comments on that but since I am single and rarely have passengers it is not a big deal for me.
This is my first time with nav so I am digging that, also think it spruces up the dash more so than the non nav. Like the heated and cooled seats and the economy, it is incredible.
