I haven't been on here at all, being my MS6 is more of just a daily driver then an actual enthusiast car, but just happened to pop in when I saw this thread. I read through it, with something VERY in common, so I wanted to respond. If you look below, you will see my past and current vehicles.
Interesting change you went through. I can tell you in case you don't already know, that the market value of the S2K has really suffered badly.
The MS6 is truly a great daily driver, and even better in the snow then my former STI. However, when it comes to fun, I can't even remotely compare it to my S2000. If you make this change, hopefully you won't find yourself in this position again, but it's fun changing around cars, and can be addictive. I finally stopped the insanity.
Looks like you have crossed all borders in daily drivers in a short amount of time, without a solution yet, but perhaps the MS6 would suit your needs. I could never drive my S2K as a daily. You may find yourself in this position again if you were to get rid of your S2K for a Mazdaspeed 6 if you end up missing that nimbleness. Going from a pure sports car to a luxury performance sedan has it's compromises, which is why I own both.
In reliability, I give the nod to the S2K, as I will be selling my Mazdaspeed 6 as soon as it reaches 50k miles and warranty is up (one year from now).
They are night and day cars, with absolutely nothing in common as you probably already know. Good luck in your search, and try not to miss the S2K too much.
