I didn't go for the 2009 car as I was determined to go with the standard 17" rims (old spec model) rather than the 18" ones
which are now standard on the SEL spec (2009). I value ride comfort over looks

. Additionally, I wasn't too bothered about the fact that on the 2009 spec. car it would allow me to use the paddle shifts in "drive" mode which is something I cannot do in my vehicle. In fact, I prefer to use the gear shift lever rather than the paddles which I think are a bit of a gimmick.
One characteristic this car exhibits that is similar to that of the GS 300 is the "free wheel" effect which gives little or no engine braking when you lift the throttle. Rather than dabbing the brake frequently when travelling in traffic, I like to knock the gear lever into sport mode and leave it in either 3rd or 4th gear to give some engine braking effect ... if that makes any sense. I do the same going downhill to check the speed of the car.
I so much prefer my IS250 to the latest incarnation of the BMW 3 Series or the Mercedes C class.
