First off, it was a Porsche Experience car (and the dealer was bragging how great that was!). Had 1,800 miles and was loaded up to $140K. Had the sport exhaust (which I simply hate - at least from the looks of it and no, the sound was not that great either).
Random thoughts
Short of being in sport plus (or whatever it is called), the M2 felt more responsive and just as quick - if not quicker. Felt is key word mind you
Car had the sport package so had the rear wheel steering - but/and, I never noticed it (did not realize it had that until I looked at the sticker a day later).
Car was raw - I liked that and... well, it kind of reminded me of my wife's Mini. The M2 felt more "refined".
Trust me, I liked the car - and it made me want to drive a 2S or GTS, but it was not something I "had" to have.
PS - lease was $10K down, $1,300 a month for 5K per year. Ouch.
PS - I honestly think a standard 911 might be a good replacement for my wife's Clubman.
