Is there any particular model year of the IS F that is the most bearable in stop-and-go rush hour traffic, particularly over hilly and poorly maintained roads? I know this is not at all the kind of situation that a sports sedan is good for, but it's unavoidable in the case of using the car as a daily driver.

 

i say at least 2010 or maybe even 2012. suspensions got improved a lot over the years. 2008 is very harsh, actually that was the main reason we decided against isf

 

All of them. Because once you hit the open road all of that is quickly forgotten.

Or spend a couple g's to soften the suspension if necessary. Everyone's butt is different when it comes to ride quality. Personally I have a 12 and have ridden in an 09, neither of which I thought were 'harsh'.

 

The "major" suspension revisions happened in the 2011 model year. Ride less harsh.

 

The newer ones are slightly softer. I have an 08 with 2012 springs and shocks. It's not a mind blowing difference.

 

I live in similar conditions, maybe worse, and I don't think the year is going to change it by much. I don't even think any of the other cars in this 'performance sedan' category will fair any better. I've had a c63 with dampening controls and it was useless in comfort. This car is very similar when it comes to unsmooth roads.

 

Eat a little more and get a phat donk, that'll cushion the road.
