You are buying the wrong car if the only purpose of you buying it is for commuting. For you, you wouldn’t be able to tell the difference between an is250 or an is-f…unless you care about bragging rights that you have an “f” and/or you plan on being a riceboy that tries to “race” Honda civic between stoplights. (Please don’t That’s just retarded). And frankly, call me biased, but when I see an is-f, I think “why?”. That IS-F is a big porker at 3780 with an automatic (no, it isn’t dual clutch). So sorry, it’s no M-competitor. I have not seen anyone bring an is-f to an autocross or track btw.
Save yourself some money. If you want an affordable sporty car, get an FR-S brand new for around $25k from LA dealers. Add a $5000 carb legal supercharger to it that will bring that 2800lb car near 300hp with a pretty flat torque curve, and call it a day. And I have seen plenty of FR-S ‘s on autocrosses and tracks.
