I appreciate James covering the steering feel in his 3rd write-up, as the forum had shown some interest in this. This is an advantage of being able to write a review while receiving some feedback on a daily basis.
In his defense, I'd admit that it is difficult to compare vehicles if you haven't driven them back-to-back or consecutively in a short period of time. We tend to use what we have become accustomed to as a base of comparison, so it would be difficult for him to accurately compare the IS and the TSX, since I believe the lasttime he said he drove one was in 2004. I've testdriven identical models at separate times and often they felt different the 2nd time around, or I'd pick up new things that I didn't notice simply because my daily driver had changed since the first time.
Both the TSX and IS250 start at ~$37k. TSX has a sunroof, leather seats, and HIDs standard, while one has to add $3650 to get the sunroof and leather in the IS250.
I would not expect Lexus to be selling a whole lot of these non-leather IS's, as the cloth seats, although some prefer over leather, look extremely out of place in the Lexus' near "best quality in class" interior. That is unless however, someone buys one of these, and has the interior re-upholstered (~$1200) aftermarket, as it is popular these days, then now you have a serious case against the TSX (provided you do not care much for HIDs, or a sunroof).
