i bought my m3 convertible about a month ago. i took me a bit to get use to it, get familiar with it and its all i expected it to be and more. you get alot of attention with it. when you drive it you know your driving a sophisticated, high level performance machine. from the steering to the clutch, to the shifter,to the seats, everything is just a great driving experience. i really cant think of any flaws. oh wait, the second cup holder is useless because the arm rest covers it. thats about it. yes you pay a premium for it even used but when you own it, you will know why. it has great resale value if there is such a thing with cars. fuel mileage is not great. outside of that its a pleasure.
convertible, exotic big boy performance, imola red seats, attention getter, easy to drive both slow and fast, fantastic high revving engine, getrag transmission, comfort, handles amazingly. nice thick steering wheel clutch/shifter harmony alot like the mini cooper s i traded in for this m3.
second cup holder, improve engine/exhaust note, fuel economy
