Went through the same decision making process early last year and opted for the C2S. I found the 2S at least as visually appealing as the 4S. I preferred having the extra boot room (there's not a lot in the first place). Handling wise, I preferred the "friskier" nature of the 2S (it is noticeably lighter through corners), although Alex is right about the lighter feel on the steering when you accelerate. This started to bother me after taking it on spirited drives especially, but on advice from many on this forum, I had a geo setup done with Chris Franklin at Center Gravity who changed the feel of the car dramatically and corrected this issue. Basically, he adjusted the wheel alignment so there is now more grip to the front wheels - it now feels very stable when cornering at higher speeds compared to before and I drive it with substantially more confidence than previously. Finally and this is very subjective, I don't like the centre strip between the tail lights. All this said, I would wholly agree with others that there is no substitute than to drive both (back to back if possible) before you choose. Good luck! Cheers.
