I am doing some research on the pros and cons of the ISF and also looking for reliability reviews. It seems the biggest con is the stiff ride but I am not that concerned about that. Consumer reports did not have much on the ISF. I did find a good review from Car and Driver titled 2008 Lexus IS F Long Term Road Test. Can anyone point me towards some good reviews on the ISF that really look at the relability? Also, any input on the drvietrain from current owners would be great.
